发明名称 Addition of continuous elements to non-woven mat
摘要 A reinforced chopped strand mat formed of a plurality of chopped reinforcement fibers and at least one continuous element positioned in a substantially parallel orientation in the machine direction is provided. In the reinforced chopped strand mat, the fibers are dispersed in a randomly oriented configuration at least partially surrounding the continuous elements. In preferred embodiments, the continuous element is either a wet continuous glass strand or a dry continuous yarn. The continuous elements are positioned within the chopped strand mat in a parallel or substantially parallel orientation and may be substantially equidistant from each other or irregularly spaced. Desirably, the continuous elements are equidistantly spaced about 0.25 inches to about 3 inches apart. The continuous elements simultaneously improve tensile strength and tear strength of the reinforced chopped strand mat. Methods of forming the reinforced chopped strand mat are also provided.
