Woven Roving is made up of bundles of unidirectional fiberglass filaments woven into a course heavy weave fabric used in fiberglass laminates to produce modulus and tensile strength through bulk and weight. The sides of the material in the warp direction have a stitched edge to prevent unraveling. Woven roving is generally used as part of a lay-up schedule alternatively with chopped strand mat to achieve the desired thickness and strength. Due to the course woven characteristic, this material will use proportionately more resin to wet out. Used alternately with chopped mat improves glass to resin ratios. ÂÂÂ
