Direct Roving For Winding, Weaving

Attributes
Glass Type: E6
Type of Size: Silane
Size Code: 328

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
