Abstract
A ballistic-resistant article comprising a composite panel having a plurality of layers of ballistic-resistant cloth woven from high tensile-strength fibers laminated together by an elastomeric adhesive material having oriented polymer chains. The resulting article is less than half the thickness of comparable threat level articles, is lighter than comparable threat level articles, and is buoyant.
Claims19
A ballistic-resistant article, comprising in combination:
- a plurality of sheets of cloth made from high tensile-strength fibers, said cloth shaped generally to the contours of the object to be protected;
- an elastic medium disposed between adjacent ones of said plurality of sheets of cloth and compressed between said plurality of sheets of cloth to a pressure ranging approximately between 10 and 15 pounds per square inch and heated to a temperature ranging approximately between 150.degree. and 190.degree. F. for approximately between 5 and 15 hours to produce a substantially rigid composite panel.
A flexible ballistic panel for use in a ballistic-resistant article, comprising:
- a plurality of cloth laminations, each woven from a high tensile-strength yarn having a tenacity of at least 20 grams per denier;
- an elastomer formed from at least one of natural rubber, synthetic rubber, and plastic colloid, disposed between each of said plurality of sheets of cloth and compressed and heated to bond said plurality of cloth laminations together into a semirigid panel;
- and
- said semirigid panel crimped at intervals along orthogonal axes to form the flexible ballistic panel.

A ballistic-resistant panel, comprising:
- a plurality of layers of ballistic-resistant cloth woven from high tensile-strength fibers and having a denier ranging from about 700 to about 1600;
- an elastomeric material between adjacent ones of said plurality of layers of cloth for bonding said plurality of alternative layers of ballistic-resistant cloth and elastomeric material, said composite laminate stretched at regular intervals to at least partially orient polymers within said elastomeric material between adjacent layers of cloth;
- and
- a carrier substantially surrounding said composite panel.
