Woven Roving Glass Fabric
Heavy plain-weave glass roving fabric for high-strength bi-directional reinforcement of GRP laminates.
Overview
Bi-directional strength. Structural reinforcement.
Woven Roving Glass Fabric is a heavy plain-weave fabric woven from E-glass rovings. Used alternately with chopped strand mat to increase the directional tensile and flexural strength of GRP laminates, particularly in structural applications.
Standard reinforcement layer in structural GRP applications such as water tanks, structural panels, and pressure vessels.
Key Features
- E-glass woven roving
