Direct Roving For Filament Winding, Weaving

398 Direct Roving is a single-end continuous roving based on E6 glass formulation. 398 is coated with a silane based sizing and specifically designed to reinforce epoxyresins and is suitable for amine or anhydride curing systems. 398 is designed for UD,biaxial, and multiaxial woven fabrics, and filament winding process.

Application:

The combination of 398 and epoxy resin delivers excellent mechanical properties andhigh modulus. 398 is suitable for prepreg and vacuum-assisted resin infusion processesto manufacture large wind blades, and also for use in FRP pipes and pressure vessels.

Features:

l  Fast and complete wet-out

l  Good end-use performance

l  Good mechanical strength and fatigue resistance in end products

l  Good abrasion resistance and low fuzz

l  Smooth package-to-package transfer

l  Excellent acid corrosion resistance
