No gel coat FRP flat sheet, used for sandwich panel and inner liner of post-industrial building.
It is a brittle material, which is easy to be damaged, broken and corroded. Compared with fibers, the matrix has much lower strength and modulus, but it can withstand large strains and is often viscoelastic and elastoplastic. It is a tough material. According to the length of the fiber, FRP can be divided into short fiber reinforced composite plastics and long fiber (or continuous fiber) reinforced composite plastics. According to fiber properties, it can be divided into high-performance fiber composite materials and engineering composite materials.
The FRP flat sheet has a surface layer with no fiber added on the surface, which makes the product have high hardness and high brightness, good appearance and resistance to UV, yellowing resistance, and can make the product surface gloss be retained for a long time, thereby greatly improving the product Weather resistance, but because the surface gel coat does not have fiber reinforcement, its surface toughness is relatively poor. When the sandwich plate is manufactured with a gel coat plate, such as the glass fiber reinforced plastic plate surface gel coat is subjected to excessive tension, it will crack.
