Woven roving is made from continuous glass fiber roving which are interlaced into heavy weight fabrics. Compatible with most resin systems. 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. Good drapeability, wet out and cost effective. With woven roving as a general rule estimate the resinreinforcement ratio at 1:1 by weight. Woven roving is available in a variety of weaves, weights, widths and finishes to suit a wide range of applications.
