COMPOSITES AND BALLISTIC RESISTANT ARMOR ARTICLES CONTAINING THE COMPOSITES

摘要

A ballistic resistant composite comprises (i) a first unidirectional layer comprising aromatic polyamide yarns arranged parallel with each other, a second unidirectional layer comprising aromatic polyamide yarns arranged parallel with each other, the yarns of the first layer having an orientation in a direction that is different from the orientation of the yarns of the second layer, (ii) at least one binding yarn binding the first and second layers together, the binding yarn being transverse to the plane of the first and second layers, (iii) a binding resin positioned between the first and second unidirectional layers and (iv) a coating on at least portions of external surfaces of the first plurality and the second plurality of yarns and filling some space between the filaments in the first plurality and the second plurality of yarns, wherein the coating comprises a viscoelastic resin, an aqueous based fluoropolymer and a blocked isocyanate.
