Fiberglass products are excellent corrosion resistant materials. Firstly, resins (phenolic plastic, epoxy resin, and polyester resin) are used to solidify them into one, resulting in a material with tensile strength comparable to steel - hence the name fiberglass.
Fiberglass products are excellent corrosion resistant materials. Firstly, resins (phenolic plastic, epoxy resin, and polyester resin) are used to solidify them into one, resulting in a material with tensile strength comparable to steel - hence the name fiberglass. You should understand a little bit here because the hardness of this product is very high. The tensile strength of fiberglass products is close to or even exceeds that of carbon steel, and the specific strength can be compared to high-grade alloy steel. Therefore, it has achieved remarkable results in aviation, rockets, spacecraft, high-pressure vessels, and other products that require weight reduction. FRP is a good corrosion resistant material that has good resistance to atmospheric, water, and general concentrations of acids, alkalis, salts, as well as various oils and solvents. However, its drawbacks are also obvious, that is, its long-term and high-temperature resistance is relatively poor. Generally, FRP cannot be used for a long time at high temperatures. Universal polyester FRP has a significant decrease in strength above 50 ℃, and is generally only used below 100 ℃. Universal epoxy FRP has a significant decrease in strength above 60 ℃.
