Low weight and high durability soft body armor composite using silicone-based topical treatments
View Patent ↗Ballistic resistant articles having abrasion resistance. Particularly, abrasion resistant, ballistic resistant articles and composites having a silicone-based topical treatment.
1. A method of forming an abrasion resistant composite, comprising:
i) providing a plurality of non-woven, coated fiber plies, each fiber ply comprising a plurality of fibers having a tenacity of about 7 g/denier or more and a tensile modulus of about 150 g/denier or more; the surfaces of each of said fibers of each fiber ply being substantially coated with a non-silicon-containing material;
ii) applying an uncured, silicon-containing material onto at least a portion of at least one of said coated fiber plies; and thereafter
iii) subjecting said plurality of non-woven, coated fiber plies and the uncured, silicon-containing material to heat under conditions sufficient to consolidate the plurality of non-woven, coated fiber plies into a monolithic structure, and whereby the uncured, silicon-containing material is cured and solidified on an outside surface of the monolithic structure, thereby forming the abrasion resistant composite; and wherein said abrasion resistant composite including the cured and solidified silicon-containing material has an areal density of from about 1000 g/m 2 (0.2 lb/ft 2 ) to about 40,000 g/m 2 (8.0 lb/ft 2 ), and
wherein the non-silicon-containing material is coated directly on substantially all the surface area of each individual fiber of said fibrous substrate and said silicon-containing material is applied on top of the non-silicon-containing material coating, and wherein said silicon-containing material comprises from about 0.01% to about 5.0% by weight of said composite.
