398 Direct Roving is a single-end continuous roving based on E glass formulation.It iscoated with a silane-based sizing,specifically designed to reinforce epoxy resin,andsuitable for amine or anhydride curing systems.398 is mainly used for UD,biaxial,andmultiaxial weaving processes,and also for filament winding.
398 reinforced epoxy resin has excellent mechanical properties,especially high modulus.It can be used to manufacture largewind blades in a vacuum-assisted resin infusion processes,and also to make FRP pipes and pressure vessels.
Product Features
- Smooth run-out and good process performance
- Fast and complete wet-out
- Good abrasion resistance and low fuzz
