What are the FRP product processes?

Filament Winding Process

Traditional Filament Winding

In the filament winding process, continuous strands of resin-impregnated glass fiber are wound under tension onto a mandrel in precise geometric patterns to build up the part which is then cured to form the finished parts.

Continuous Filament Winding

Multiple laminate layers, composed of resin, reinforcement glass and other materials are applied to a rotating mandrel, which is formed from a continuous steel band continuously traveling in a cork-screw motion. The composite part is heated and cured in place as the mandrel travels through the line and then cut into a specific length with a traveling cut-off saw.
