ABSTRACT:
Complex woven material as reinforcement for forming layered resin impregnated articles which are resistant to catastrophic damage from shock or local impact as from a hard object, comprised of woven bands or strips of high modulus fibers such as carbon or graphite fibers, separated in at least one direction of the material, from each other by woven bands or strips of low modulus fibers such as glass fibers, and which in a preferred embodiment are narrower than the strips of high modulus fibers. Superimposed layers of such materials can be formed, wherein the strips of high modulus fibers and low modulus fibers in the respective layers are at different angles. Such woven materials, e.g. in the form of a layered assembly, are impregnated with a suitable thermosetting resin such as an epoxy resin, and cured, to produce a layered resin impregnated article having improved damage tolerant physical and mechanical properties.
