Due to the low modulus of elasticity of glass fiber reinforced plastic, the glass fiber reinforced plastic sculpture will be easily deformed and damaged. (The elastic modulus of Fiberglass is two times larger than that of wood, but 10 times smaller than steel (E = 2.1E5), so it is often felt rigid in product structures Insufficient, easy to deform.)

Solution: We can make the Fiberglass sculpture into a thin shell structure or a sandwich structure, or we can make up for the deformation by using high-modulus fibers or reinforcing ribs.

Fiberglass Sculpture Warranty Period and Elastic Effect

Fiberglass Sculpture Warranty Period and Elastic Effect

The lightweight and high-strength properties of Fiberglass are derived from the lower resin density (the density of the cast body is about 1.27) and the high tensile strength of glass fiber (more than 5 times that of ordinary steel). The density of Fiberglass varies with the resin content. From high-resin content glass felt products to low-resin content Fiberglass wound products (density 2.2), the density of Fiberglass is only 1 / 4-1 / 5 of ordinary carbon steel, which is about 1/3 lighter than aluminum. When the glass is melted at high temperature and rapidly drawn into filaments, due to the increase in specific surface area, large defects are difficult to exist inside and on the glass fiber, so the strength of the glass fiber is very high. The alkali-free aluminoborosilicate fiber is commonly used.
