Filament winding roving is mainly compatible with unsaturated polyester, polyurethane, vinyl, epoxy and phenolic resins, etc. Its final composite product delivers excellent mechanical properties.

Traditional 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 cured to form the finished composites.
Continuous process: Multiple laminate layers, composed of resin, reinforcement glass and other materials are applies to a rotating mandrel, which is formed from a continuous steel band continuously traveling in a cork-crew 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.
