The strength of the FRP grille is secret

The strength of FRP grilles is so great that many people wonder why this non-glass and non-steel material has such strength.

GFRP is a composite material, mainly made of resin and glass fiber, with different proportions and different densities. The density of the resin is about 1.0, the density of glass fiber is about 2.6, and the density of most common GFRP materials is between 1.6 and 2.0.

Seeing the above data, many people have guessed that the advantage of composite materials is that they combine the advantages of both sides to show other advantages.
