The use and application of glass fiber reinforced plastic

                         The use and application of
FRP FRP is a composite material that has developed rapidly in the past 50 years. 70% of the output of glass fiber is used to make glass fiber reinforced plastic. FRP has high hardness and is much lighter than steel. It is used in jet planes as fuel tanks and pipes to reduce the weight of the plane. The astronauts who landed on the moon, the miniature oxygen cylinders on their backs, are also made of fiberglass. FRP is easy to process, rust is not rotten, no paint is required. my country has widely used FRP to manufacture various small motor boats, lifeboats, yachts, and automobile manufacturing, saving a lot of steel.
Because FRP is a kind of composite material, its performance adaptability is very wide, so its market development prospect is very broad. According to relevant statistics, there are about 40,000 types of FRP products developed by countries around the world. Although each country has its own emphasis on the direction of development according to its own economic development, basically all industrial sectors have been involved. After more than 40 years of development, my country's glass fiber reinforced plastic industry has also achieved successful application in various fields of the national economy and played an important role in economic construction. The main application fields of FRP are roughly summarized as follows:
Construction industry: cooling towers, FRP doors and windows, building structures, building envelopes, indoor equipment and decorative parts, FRP panels, corrugated tiles, decorative panels, sanitary ware and overall bathrooms , saunas, surf baths, building construction templates, warehouse buildings, and solar energy utilization devices, etc.
Chemical and chemical industry: corrosion-resistant pipelines, storage tanks and storage tanks, corrosion-resistant transfer pumps and their accessories, corrosion-resistant valves, grilles, ventilation facilities, and sewage and wastewater treatment equipment and accessories, etc.
Automobile and railway transportation industry: automobile shells and other components, all-plastic miniature cars, body shells, doors, inner panels, main pillars, floors, sills, bumpers, instrument panels, small vans, and large passenger cars Fire trucks, refrigerated trucks, tractor cabs and machine hoods, etc.; in terms of railway transportation, there are train window frames, interior roof bends, roof water tanks, toilet floors, luggage car doors, roof ventilators, refrigerated car doors, Water storage tanks, and some railway communication facilities, etc.; in road construction, there are traffic road signs, road signs, isolation piers, highway guardrails, etc.
FRP boats and water transportation industry: inland passenger and cargo ships, fishing boats, hovercraft, all kinds of yachts, racing boats, high-speed boats, lifeboats, traffic boats, and FRP beacon buoys and mooring buoys, etc. Electrical industry and communication engineering: arc extinguishing equipment, cable protection tube, generator stator coil and support ring and cone shell, insulating tube, insulating rod, motor guard ring, high-voltage insulator, standard capacitor shell, motor cooling bushing, power generation Strong electrical equipment such as windshields; electrical equipment such as distribution boxes and switchboards, insulating shafts, glass fiber reinforced plastic covers; printed circuit boards, antennas, radomes and other electronic engineering applications. In recent years, with the development of science and technology and the improvement of people's living standards, many civilian FRP products have been developed in large quantities, such as many urban sculptures, arts and crafts modeling, fast dining tables and chairs, motorcycle parts, FRP flower pots, safety helmets, Advanced amusement equipment, housings for household appliances, etc., have been successfully used in a large number of applications.
It can be used to make glass fiber reinforced plastic tiles, also known as transparent tiles. It is a lighting material used in conjunction with steel structures. It is mainly composed of high-performance upper film, reinforced polyester and glass fiber. The upper film should have good anti-ultraviolet and anti-static properties. Anti-ultraviolet is to protect the polyester of FRP lighting board from yellowing and aging, and premature loss of light transmission characteristics. Antistatic is to ensure that the dust on the surface is easily washed away by rain or blown away by the wind, and maintain a clean and beautiful surface. Due to its stable quality and durable characteristics, it is very popular among customers. The product can be widely used in industrial/commercial/civil building roofs and walls, and as props in the
film industry, which is convenient and cost-effective. Can imitate many kinds of material effects. By people's welcome. Chemical plants also use phenolic resin glass fiber reinforced plastics instead of stainless steel for various corrosion-resistant equipment, which greatly prolongs the life of the equipment. FRP is non-magnetic and does not block the passage of electromagnetic waves. Using it as the radome of the missile is like putting on a pair of protective glasses for the missile, which does not block the "line of sight" of the radar, but also plays a protective role. Today, the radomes of many missiles and ground radar stations are made of fiberglass.
In the 21st century, according to the good wave transmittance and performance of FRP, with the widespread popularity of mobile phone communications, FRP is widely used in the manufacture of 2G and 3G antenna covers. FRP is known for its good formability and appearance. Beautification, has played a very good role in the beautification of the community. The products in this area include square column line covers, artificial stones, and beautification trees used in the field. FRP has also made great contributions to improving the water of sports. Since the sport of pole vaulting, the highest record created by an athlete using a wooden pole is 3.05 meters. Later bamboo poles were used. By 1942, the record was raised to 4.77 meters.
The advantage of bamboo poles is that they are light and flexible. The disadvantage is that the lower end is thick and the upper end is thin. It is very difficult to improve the record. Therefore, people use aluminum alloy poles instead of bamboo poles. Although it is light and strong, it lacks elasticity. In this way, from 1942 to 1957, in 15 years, the highest record for pole vault was only raised by 1 cm. But since the appearance of the new fiberglass pole, because it is light and flexible, the record has risen rapidly, and today's pole vault record has exceeded the 6-meter mark. Today, glass fiber reinforced plastic is also widely used in people's lives. People affectionately call it "glass fiber reinforced plastic". Because some of its special varieties can still retain many advantages of glass, such as transparency, people use it as window glass. , which can not only block the ultraviolet rays in the sun, but also make the room bright. People also use it to make various sturdy and durable daily necessities. Such as bathroom utensils, kitchen utensils, toilet utensils, etc.
2. Market
application FRP is a kind of composite material. Because of its unique performance advantages, FRP material has been used in aerospace, railway, decorative construction, home furniture, advertising display, craft gifts, building materials and bathroom, yacht mooring, sports materials It has been widely used in more than ten industries related to sanitation engineering, etc., and has been highly praised, becoming the darling of the needs of merchants in the new era in the material industry.
