Functional characteristics of FRP products

- Jul 02, 2020-

FRP products are good corrosion-resistant materials. First of all, resins (phenolic plastics, epoxy resins and polyester resins) are used to condense them into one. The resulting material has a tensile strength comparable to that of steel-hence the name FRP . Everyone should understand a bit here, because the hardness of this product is very high.

The tensile strength of FRP products is close to or even higher than that of carbon steel, and the specific strength can be compared with high-grade alloy steel. Therefore, it has excellent results in aviation, rockets, space vehicles, high-pressure containers and other products that need to reduce their weight. FRP is a good corrosion-resistant material, and it has good resistance to the atmosphere, water and general concentrations of acids, alkalis, salts, and various oils and solvents. However, its shortcomings 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. The strength of general-purpose polyester FRP is significantly reduced above 50 ℃, and generally only used below 100 ℃. General-purpose epoxy FRP above 60 ℃, the strength has decreased significantly.
