As a high-performance composite material, fiberglass reinforced plastic (FRP) has attracted widespread attention in the national economy for its unique physical and chemical properties. Using FRP-related product applications as an example, RUNSING will systematically analyze the material's six major technical advantages and industrial application scenarios.​ Lightweight and High-Strength: Looking at aircraft and wind turbine blades, composite materials will challenge your perception.​ FRP materials have a density range of 1.4-2.0 g/cm³, achieving a 60-80% weight reduction compared to traditional metal materials.​ Take the aircraft sector as an example. The fuselage of a rescue helicopter is made of composite materials such as carbon fiber, glass fiber, and resin. Each propeller blade is 5 meters long and weighs 40 kilograms. The main rotor has four blades, rotates at 380 rpm, and can withstand a tensile force of 20 tons. Do you know what materials they are made of? The propeller blades are also made of composite materials such as carbon fiber, glass fiber, and resin, filled with rigid foam. They are lightweight, high-strength, and lack the fatigue characteristics of metal. Composite materials account for 24% of the weight of top-tier US fighter jets, while the proportion in my country is 27%. The Boeing 787 uses nearly 50% of its fuselage structure weight. The most striking feature of the Boeing 787 Dreamliner is its fuselage and major wing components, which extensively utilize lighter, stronger composite materials instead of the currently common aircraft aluminum alloys. This significantly reduces the aircraft's weight, saves fuel, and is more environmentally friendly. Composite materials are also less susceptible to fatigue and corrosion than aluminum alloys, reducing maintenance costs and extending the aircraft's lifespan, with a target lifespan of 50 years. Replacing aircraft aluminum with composite materials allows for larger windows and longer wings. The increased span ratio provides greater lift, which naturally results in lower energy consumption, or greater fuel efficiency. For example, long-endurance drones with aspect ratios of 25 can achieve flight times of up to 40 hours.​ Take the wind power industry as an example. Let's look at wind turbine blades to understand the strength and service life of fiberglass. Wind turbine blades and nacelles are made of fiberglass composite materials. By 2022, the rotating diameter of wind turbine blades has reached 220 meters, with individual blades exceeding 120 meters in length and weighing an astonishing 50 tons. The design life of wind turbine blades and nacelles is generally 20 years. Depending on the material, process, and operating environment, the service life of fiberglass reinforced plastics is generally 10-50 years.​ The wind turbine blades appear to rotate slowly, but what's surprising is that the blade tips are moving at speeds comparable to those of steel. Can you imagine that? Onshore wind turbine blades are typically 90-100 meters long, while offshore wind turbine blades are 100-120 meters or even longer. Onshore wind turbine blades rotate 10-20 times per minute, while offshore wind turbine blades rotate 10-15 times per minute. Assuming a blade length of 120 meters and a speed of 15 revolutions per minute, the tip speed is 678 kilometers per hour. Can you imagine that?​ Excellent Corrosion Resistance: A Look at Luxury Yachts​ Fiberglass (FRP) is primarily composed of glass fiber and resin, making it resistant to corrosion from acids, alkalis, salts, seawater, untreated sewage, corrosive soil or groundwater, and numerous chemical fluids. By selecting different types of resin, FRP products can be manufactured with robust corrosion resistance against a wide range of strong acids, bases, and salts.​ Take luxury yachts as an example to understand the outstanding corrosion resistance of FRP. Corrosion resistance is FRP's strength. Motorboats, racing boats, fishing boats, luxury yachts, and even sailboats are primarily made of FRP. Its lightweight, high-strength, corrosion-resistant, and easy-to-repair and maintain properties make it a popular choice. In February 2021, Italy's Benetti S.p.A. announced the sale of its fourth Diamond 145-class ultra-luxury yacht. This 44-meter FRP yacht has an internal volume of 456 gross tons.​ FRP has the following advantages over other materials in terms of seawater corrosion resistance:​ Superior to carbon steel and low-alloy steel: Carbon steel and low-alloy steel are susceptible to electrochemical corrosion in seawater, while FRP is highly resistant to corrosive media such as chloride ions in seawater and does not suffer from electrochemical corrosion.​ Superior to some stainless steels**: Although stainless steel has good corrosion resistance in general marine environments, some types of stainless steel may experience pitting and crevice corrosion in seawater containing high levels of chloride ions, while FRP offers more stable corrosion resistance.​ Superior to aluminum and copper alloys: Aluminum and copper alloys can also corrode in seawater, especially under certain electrolyte conditions, while FRP resists a wider range of corrosive media.​ Comparison with other non-metallic materials​ 4.1 Superior to wood: Wood is susceptible to corrosion and insect damage in seawater, while FRP is immune to these conditions and has a longer service life.​ 4.2 Superior to plastic: Some plastic materials are prone to aging and degradation in seawater, while FRP offers better weather and aging resistance, maintaining stable performance over time.​ Excellent Insulation Performance: Dielectric strength reaches 20 kV/mm, thermal conductivity 0.2 W/(m·K).​ FRP material has a volume resistivity of >1×10¹³Ω·cm, meeting the IEC 60093 insulation standard. In the 5G communications field, wave-transparent FRP radomes achieve electromagnetic losses of

Fiberglass reinforced plastic (FRP), a new composite material, has been widely used in construction, shipbuilding, transportation, chemical engineering, and other fields due to its excellent mechanical properties, corrosion resistance, and insulation properties. In practical use, the flame retardancy of FRP has become a key safety consideration. With increasing fire safety requirements, the flame retardancy of FRP and related industry standards have received increasing attention. I. Flame Retardancy of FRP Sheets 1. Composition and Flame Retardancy Mechanism of FRP FRP (glass fiber reinforced plastic) consists of glass fiber and resin (such as unsaturated polyester or epoxy resin). While glass fiber itself has strong high-temperature resistance, the resin is the key factor affecting its flame retardancy. The flame retardancy of the resin depends primarily on its chemical composition and the addition of flame retardants. Typically, flame retardants are added to resins to enhance their fire resistance. These flame retardants decompose under the influence of a fire source, releasing cooling gases that effectively slow the spread of flames. 2. Specific manifestations of flame retardant properties The flame retardant properties of FRP sheets are manifested in their ability to delay the combustion process in high-temperature environments and reduce the speed of flame spread. Depending on different application requirements, the flame retardant grades of FRP vary. Generally speaking, FRP sheets with better flame retardant properties can provide longer time for evacuation and self-rescue when a fire occurs, which is crucial for the safety of public buildings, ships and vehicles. 3. Common flame retardant treatment methods In order to improve the flame retardant properties of FRP sheets, common treatment methods include: (1) Adding flame retardants: By adding inorganic or organic flame retardants, such as ammonium chloride, phosphate, etc., the flame retardancy of the resin is improved. (2) Surface coating of flame retardant paint: Applying a layer of flame retardant paint on the surface of the FRP sheet can effectively prevent the spread of flames. (3) Modified resin: Using a special resin formula to improve the flame retardant properties of FRP. For example, using resins containing elements such as halogens and phosphorus. II. Industry Standards for FRP Sheets Flame retardant performance standards for FRP sheets are primarily established by national and industry organizations to ensure their safety in various applications. The following are several key standards related to the flame retardancy of FRP sheets: (I) Chinese Flame Retardant Standards GB 8624-2012, "Classification of Combustion Behavior of Building Materials and Products": categorizes the combustion performance of materials into A (non-combustible), B1 (difficult to burn), B2 (combustible), and B3 (combustible). GB/T 2408-2021, "Determination of Combustion Behavior of Plastics" GB/T 4189-2022, "Plastics - Combustion Behavior - Medium-Sized Fire Tests on Fiber-Reinforced Polymer Composites" GB/T 5169, based on IEC standards, is used for fire hazard testing of electrical and electronic products. GB 8410-2006 "Combustion Characteristics of Automotive Interior Materials" (II) European Flame Retardant Standards EN 13501-1 "Classification of Burning Behavior of Building Products": Adopts the Euroclass classification (A1-F), taking into account heat of combustion, smoke, and dripping. EN 45545-2013 (III) US Flame Retardant Standards ASTM E84 "Surface Burning Characteristics Test": Determines the Flame Spread Index (FSI) and Smoke Index (SDI). NFPA 701 "Test Methods for Flame Retardancy of Textiles and Films": Applicable to curtains, drapes, etc. UL 94 "Test Methods for Flammability of Plastic Materials": Classifies them into HB, V-0/V-1/V-2 grades, evaluating vertical/horizontal burning performance. UL 746: Evaluates the long-term flame resistance of plastics. According to GB 8624-2012, the current mainstream flame-retardant products in the domestic FRP sheet market are B1 and B2 grades. The specific classification criteria are as follows: Runsing's flame-retardant FRP products meet the ASTM E84 Class A standard, significantly exceeding Class B1 flame retardancy. Product testing meets both ASTM E84 and the national standard GB/T 4189-2022, "Plastics—Fire Behavior—Medium-Sized Fire Resistance Tests for Fiber-Reinforced Polymer Composites" (Runsing participated in the development of this national standard).​ III. The Importance of Flame Retardancy in Practical Applications of FRP Sheets​ The flame retardancy of FRP sheets is crucial in many fields, particularly in the following applications:​ Construction: Since FRP sheets are widely used in exterior walls, interiors, and ceilings, ensuring their flame retardancy meets relevant standards is fundamental to building safety.​ Marine: FRP materials used in ship interiors must provide sufficient flame retardancy in the event of a fire to ensure the safe evacuation of crew members.​ Transportation: In transportation, including aviation, railways, and subways, the flame retardancy of FRP sheets can effectively prevent the spread of fire and ensure passenger safety.​ Power and chemical industries: The FRP sheets used in these industries must not only meet the requirements of strength and corrosion resistance, but also ensure their flame retardant properties to avoid fire disasters.

FRP, a high-performance composite material, is widely used in modern industry and construction due to its exceptional corrosion resistance, strength, and lightweight properties. Its water resistance is particularly advantageous in water and humid environments. ​ I. Composition and Water Resistance of FRP​ FRP, also known as fiberglass reinforced plastic, is a material made by combining glass fiber and resin through a composite process. While glass fiber itself possesses excellent water resistance, the choice of resin and the use of additives determine FRP's water resistance.​ Glass Fiber: Glass fiber is an inorganic material with a stable molecular structure that is not easily absorbed by water. This property of glass fiber enables FRP to resist water penetration and long-term immersion, maintaining its structural stability.​ The Role of Resin: Resin is a crucial component of FRP, and different types of resin have varying water resistance. Common FRP resins include unsaturated polyester resin, epoxy resin, and phenolic resin, with epoxy resin offering the best water resistance. By optimizing the resin formula, the stability of FRP in aqueous environments can be significantly improved.​ II. Testing Standards for FRP Water Resistance​ To scientifically evaluate FRP's performance in water, the industry has established a series of testing standards. These tests primarily focus on FRP's resistance to water penetration, water absorption, and changes in physical properties after long-term exposure in various aqueous environments.​ Water Absorption Test: Water absorption is a key indicator of FRP's water resistance. FRP with a low water absorption rate can maintain good performance over time, making it particularly suitable for humid environments or locations subject to prolonged immersion in water.​ Immersion Test: FRP samples are immersed in water for a specified period of time to test for changes in strength, surface damage, and changes in physical properties after water absorption. This test can be used to assess the FRP's reliability in aqueous environments.​ Long-Term Exposure Test: The water resistance of FRP depends not only on its initial performance but also on changes in performance over time. Therefore, long-term exposure testing (such as testing in high-humidity and high-temperature environments) is a key step in verifying the performance of FRP materials.​ III. FRP's Water Resistance Advantages​ FRP's water resistance has enabled it to be widely used in various industries, especially in aquatic environments, where it offers unparalleled advantages.​ Water Corrosion Resistance: FRP exhibits excellent water corrosion resistance. Compared to traditional metal materials, FRP is more resistant to water corrosion. In aquatic structures such as ships and offshore platforms, FRP not only prevents water erosion but also reduces structural damage caused by corrosion, extending its service life.​ Durability: FRP exhibits far superior durability in aquatic environments. Even after prolonged exposure to water, FRP maintains its original strength and toughness, remaining unaffected by water. This makes FRP an ideal choice for underwater projects such as building facades, underground pipelines, and sewage treatment facilities.​ Lightweight and Strong: Fiberglass is not only water-resistant but also lighter than other materials, making it advantageous for use in engineering projects. Its lightweight nature makes transportation and installation easier, especially in environments exposed to water for extended periods, where its portability reduces structural burden.​ IV. Typical Applications of Fiberglass​ Due to its superior water resistance, fiberglass is widely used in a variety of applications, particularly those frequently exposed to moisture or underwater.​ Shipbuilding and Offshore Engineering: Due to its excellent water corrosion resistance and lightweight properties, fiberglass is widely used in the construction of ships and offshore platforms. In these applications, fiberglass not only resists seawater corrosion but also withstands complex water pressures and environmental challenges.​ Water Treatment Equipment: In sewage treatment plants and water treatment equipment, fiberglass is often used to manufacture components such as pipes, storage tanks, and reaction tanks. Since these equipment are exposed to water for extended periods, fiberglass's water resistance ensures long-term, stable operation.​ Construction and Infrastructure: Fiberglass reinforced plastics (FRP) are widely used in building exterior walls, roofs, and piping systems in underground structures, coastal buildings, and high-humidity environments due to their water resistance. This water resistance ensures the long-term stability and safety of the building.​ Aquaculture: Runsing's products, engineered with specialized processes, are widely used in aquaculture, particularly marine aquaculture and industrialized marine aquaculture. They solve numerous industry challenges, reduce maintenance costs, extend service life, and create value for customers.
