Abstract:
A multilayer complex armor having a hard impact layer formed of a plurality of ceramic bodies bound to a surface of a backing layer, a peripheral hard impact layer retaining means positioned about the outer periphery of said hard impact layer, and peripheral ceramic body retaining means positioned about the periphery of each of said ceramic bodies.
Abstract:
This invention relates to a fire retardant compound comprising at least one fibrous layer comprising a network of fibers (12) such as high strength polyethylene or aramid fibers in a matrix such as a blend of a vinyl ester and a polyurethane, and a fire retardant layer (14) comprised of a particulate fire retardant material which decompose and heating to a gaseous material such as magnesium hydroxide dispersed in a matrix comprised of a relatively high char yield resin such as a cured phenolic cyanate resin.
Abstract:
A multilayer armor (40) comprising a hard ceramic impact layer (12), a vibration isolating layer (14) position adjacent to said hard impact layer (12) and in contract therewith, and a backing layer (16) attached to said vibration isolating layer (14) on the side opposite the side thereof attached to the hard impact layer (12).
