Filament Winding

Resin-impregnated continuous strands (woven roving, mat, or impregnated roving) are wound onto a mandrel in specific patterns and then cured to form the finished products. it includes discontinuous filament winding and continuous filament winding.

Fiberglass Products for Filament Winding

• Direct Roving for Filament Winding

  An intermediate molding process where fiberglass reinforcements (roving or fabrics) and resins are impregnated evenly and partially cured as pre-formed materials, which can be directly processed tor final products without adding more resin.
