E-Glass Woven Roving (WR) is bidirectional and enhanced fabric made by interweaving direct roving which is leaked by 2000 hole board in plain weave pattern. Glassfiber woven roving is compatible with unsaturated polyester, vinyl ester epoxy and phenolic resins.
E-Glass Woven Roving is used in most cases to increase the flexural and impact strength of laminates. Ideal for multi-layer hand lay-up applications where great material strength is required.Woven Roving is available in a variety of weaves, weights, widths and finishes to suit a wide range of applications.
