E-glass Assembled Roving For Chopping
E-glass Assembled Roving For Chopping
Assembled Roving for Chopping is coated with special silane-based sizing, compatible with UP and VE, delivering relatively high resin absorbability and excellent choppability, while its final composite products deliver superior water resistance and excellent chemical corrosion resistance.
Features
●High resin absorbability
●Excellent choppability
●Superior water resistance
● excellent chemical corrosion resistance of final products

Application
It is typically used to manufacture FRP pipes.

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 .
