Fibreglass Research Chop Strand Double Bias Roving

Chop Strand Mat is a general purpose reinforcement material. It is composed of chopped fiberglass of various lengths randomly dispersed to provide equal distribution in all directions, held together with a chemical binder. The end result is a material that creates good stiffness in products when used alone or in conjuction with other fiberglass fabrics. Chop Strand Mat is commonly used because of its low cost and the good bond provided between layers of Woven Roving or fiberglass cloth. It is also commonly used by itself for a wide variety of glassing applications where a thick, heavy, durable, coarse finish is required. Chop Strand Mat is usually categorized by weight per square foot.In most cases the materials are usually a Woven Material or Cloth for high tensile strength along with Chop Strand Mat to reduce labor cost.
The resulting DOUBLE BIAS product is extremely conformable with high strength offering fast wet out. Ideal for hand lay up molding, resin infusion, SRIM, RRIM, and SCRIMP processes. Compatible with polyester, Vinyl Ester, Epoxy, and Polyurethane resin systems. Great for fiberglassing stringers and bulk heads because it will lay down nicely. Heavy duty fiberglass reinforcement common in marine construction. Used where high strength and fast build-up are necessary.
