Abstract
Abstract Improved unidirectional webbing material having a low warp to fill weight ratio and comprised of specially coated and spaced generally parallel warp or carrier strands of a synthetic fiber such as fiber glass interwoven with and securely bonded to spaced groupings of glass fiber weft (fill) elements to provide a distortion resistant and rugged fabric useful for the reinforcement of molded plastic articles and the like.
