Abstract
Abstract A reinforcing structural material is provided made of a plurality of fiber assembly cords interwoven into a braid, each of the cords being comprised of a plurality of fibers, and the braids being impregnated with a bonding agent for bonding together the fibers and cords. The reinforcing braid is useful for reinforcing a fibrous inorganic composite providing a product which is light in weight but excellent in strength characteristics.
