E-glass Assembled Roving For Filament Winding Assembled Roving for Filament Winding is specially designed for FRP filament winding process, compatible with unsaturated polyester. Its final composite product delivers excellent mechanical property. Features ●Excellent mechanical property ●Fast wet out in resins ●Low fuzz Application It is mainly used to manufacture storage vessels and pipes in petroleum, chemical and mining industries. Filament Winding Process Traditional Filament Winding In the filament winding process , continuous strands of resin-impregnated glassfiber are wound under tension onto a mandrel in precise geometric patterns tobuild 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 .
