328 Direct Roving is based on E6 glass formulation, coated with a silane-based sizing.It is specifically designed to reinforce both amine and anhydride cured epoxy resins.328 is designed to manufacture UD, biaxial, and multiaxial woven fabrics.
Application:
328 is suitable for use in vacuum-assisted resin infusion processes to manufacture largewind blades.
Features:
l Good compatibility with epoxy resin
l Fast, uniform and complete wet-outand wet-through
l Good abrasion resistance,low fuzz
l Excellent mechanical properties
l Excellent acid corrosion resistance
