The use of FRP

FRP is a composite material that has developed rapidly in the past fifty years. 70% of the output of glass fiber is used to make FRP. FRP has high hardness and is much lighter than steel. It is used as fuel tanks and pipes on jet aircraft to reduce the weight of the aircraft. Astronauts on the moon, the miniature oxygen cylinders on their backs are also made of fiberglass. FRP is easy to process, stainless and not rotten, and does not require paint. my country has widely used FRP to manufacture various small motorboats, lifeboats, yachts, and automobile manufacturing industries, saving a lot of steel. Since FRP is a composite material, its performance can be adapted to a wide range, so its market development prospect is very broad. According to relevant statistics, the types of FRP products developed by countries around the world have reached about 40,000. Although each country has its own development direction according to its own economic development, it has basically involved various industrial sectors. After more than 40 years of development, my country's FRP industry has also achieved successful applications 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:
1. Construction industry: cooling towers, FRP doors and windows New, building structures, enclosure structures, indoor equipment and decorative parts, FRP flat panels, corrugated tiles, decorative panels, FRP cover panels, sanitary ware and overall toilets, saunas, surfing bathrooms, Building construction formwork, storage building, concrete formwork, reinforcement and solar energy utilization devices, etc.
2. Chemical and chemical industry: corrosion-resistant pipelines, storage tanks, corrosion-resistant delivery pumps and their accessories, corrosion-resistant valves, grilles, ventilation facilities, and sewage and waste water treatment equipment and their accessories, etc.
3. Automobile and railway transportation industry: automobile shell and other parts, all-plastic miniature cars, car body shells, doors, inner panels, main pillars, floors, bottom beams, bumpers, instrument panels of large passenger cars, small vans , as well as fire tank trucks, refrigerated trucks, tractor cabs and machine covers, etc.
4. In terms of railway transportation, there are train window frames, inner roof bending plates, roof water tanks, toilet floors, luggage car doors, roof ventilators, refrigerated car doors, water storage tanks, and some railway communication facilities.
5. In terms of road construction, there are traffic road signs, isolation piers, sign piles, sign boards, road guardrails, etc., boats and water transport industries.
6. Inland river passenger and cargo ships, fishing boats, hovercraft, all kinds of yachts, racing boats, high-speed boats, lifeboats, traffic boats, and fiberglass buoys and mooring buoys, etc.
7. Electrical industry and communication engineering: arc extinguishing equipment, cable protection tubes, generator stator coils and support rings and cone shells, insulating tubes, insulating rods, motor guard rings, high-voltage insulators, standard capacitor shells, and casings for motor cooling , Generator windshield and other strong electric equipment; electrical equipment such as distribution box and switchboard, insulating shaft, glass fiber reinforced plastic cover; printed circuit board, antenna, radome and other electronic engineering applications.
