GFRP begins by combining continuous glass fibers, impregnated with tough, corrosion-and moisture-resistant polypropylene into a 0/90°degree-bi-directional structure. Then laminate a series of these substrate layers together.

Echos-GFRP is a much tougher, low cost, lighter material than FRP.

GFRP is more than twice stronger than FRP, even GFRP still lighter than FRP.
