Processes

Woven glass fabrics (Fiberex WR series) are made by weaving continuous glass fibers (Fiberex 408, 410 series or 503, 510 series) on a loom using roving of the required yield (Tex) in the warp and weft directions to result in a woven fabric of the required density. These fabrics are used in the contact molding (hand lay-up) technique of processing, generally in combination with chopped strand mat. The woven roving provide higher bi-directional strength to the molded components. They are also used in the spray up technique to provide bi-directional strength and in pultrusion as a combination mat where it is stitched to chopped strand mat.

Woven glass fabrics can also be made by use of continuous direct roving in the warp (or weft) and textured roving (Fiberex TR series) in weft (or warp) direction. Another category of woven fabrics is obtained when texturized roving are used in both the warp and weft directions to result in bulky fabrics.
