What exactly is a glass fiber reinforcement，AbbreviationFRP

Foreign friends introduce what glass reinforcement is, what products are glass fiber reinforced reinforced reinforced fiber reinforced reinforcement

1. FRP tedious

???FRP (also known as glass fiber enhanced plastics, symbols are GFRP or FRP). It is a composite material for glass fiber and its products (glass cloth, belt, felt, gauze, etc.) as an enhanced material to synthesize the resin as a foundation material. The concept of composite materials refers to one material that cannot meet the requirements of the use. It needs to be composed of two or more materials to form another material that can meet people's requirements, that is, composite materials. Due to the different varieties of resin used, it is known as the polyester glass reinforcement, epoxy glass reinforcement, and phenolic glass reinforcement.

Resin. Resin refers to a different and high relative molecular weight, solid, semi -solid or pseudo -solid, and sometimes it can also be a liquid organic matter. In a broad sense, resin is used to any polymer as a basic material of plastic. Unsaturated polyester, epoxy, phenolic resin, etc. After the polycase and heated, it will form insoluble and non -melting curing, so it is called thermosethe resin; It is heated again, so it is called thermoplastic resin, which is often referred to as plastic.

2. Features of FRP (FRP)

(1) FRP (FRP) light quality

???The relative density is between 1.5 and 2.0, only 1/4 ~ 1/5 of carbon steel, but the stretching strength is close, or even more than carbon steel, and the comparison of strength can be compared with high -grade alloy steel. Therefore, it has excellent results in aviation, rockets, cosmic aircraft, high -pressure containers, and other products that need to reduce self -weight. Some epoxy FRP stretch, bending, and compression strength can reach more than 400MPa.

(2) FRP (FRP) has good corrosion resistance

????FRP is a good corrosion -resistant material, which has good resistance to the atmosphere, water and general concentration of acid, alkali, salt, and multiple oils and solvents. It has been applied to all aspects of chemical anticorrosion, and is replacing carbon steel, stainless steel, wood, non -ferrous metals, etc.

(3) FRP (FRP) has good electrical performance

????It is an excellent insulating material that is used to make the insulator. Under high frequency, good dielectric can be protected. Microwaves are well used for radar antenna cover.

(4) FRP (FRP) has good thermal performance

????The FRP has a low thermal guidance rate, and the room temperature is 1.25 ~ 1.67kj/(m · H · K). Only the metal's 1/100 ~ 1/1000 is the excellent heating material. In the case of instantaneous ultra -high temperature, it is the ideal thermal protection and obscure materials, which can protect the cosmic aircraft with high -speed airflow scouring above 2000 ° C.
