1. Fiberglass (Fiberglass), also known as gFiberglass, is a fiber-reinforced plastic, generally referred to as glass fiber reinforced unsaturated polyester, epoxy resin, and phenolic resin matrix. A reinforced plastic made of glass fiber or a product thereof is used as a reinforcing material, called glass fiber reinforced plastic, or glass fiber, unlike tempered glass.
2. Classification: According to the fiber used, it can be divided into glass fiber reinforced composite material (Fiberglass), carbon fiber reinforced composite material (fiberglass) and boron reinforced composite material. It is a composite material made of glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as a reinforcing material and synthetic resin as a matrix material. The fiber-reinforced composite material consists of reinforcing fibers and a matrix. The diameter of the fiber (or whisker) is very small, generally below 10 μm, the defects are getting smaller and smaller, and the strain at break is about 30%. It is a fragile material that is susceptible to damage, breakage, and corrosion. The matrix has a much lower strength and modulus than the fiber, but can withstand large strains, often viscoelastic and elastoplastic, and is a ductile material.
3. Performance: The glass has high hardness, but the performance is fragile, the transparency is good, the high-temperature resistance, the corrosion resistance, etc.; at the same time, the steel is very hard, not easy to break, and has the characteristics of high-temperature resistance.
