Polyolefin fiber reinforced rubber

摘要

Rubberized polyolefin fabrics, particularly rubberized polyolefin fiber containing fabrics and a method for vulcanizing rubber without melting or lowering the performance of the fibers. A plurality of fibrous layers are molded and rubberized under high pressures, producing fabrics having customized stiffness properties.

主权项

1. A rubberized, molded ballistic resistant fabric comprising a plurality of woven fibrous layers comprising polyolefin fibers or a plurality of non-woven fibrous layers comprising polyolefin fibers, or a combination of at least one woven fibrous layer and at least one non-woven fibrous layer of polyolefin fibers; said fabric having a stiffness of from about 20 ksi to about 500 ksi as measured by ASTM D790; and said polyolefin fibers having a tenacity of about 7 g/denier or more and a tensile modulus of about 150 g/denier or more; said fabric having a vulcanized rubber composition attached or applied to at least one surface thereof; wherein the fibers forming the fibrous layers are not embedded within or encapsulated by the rubber composition, wherein the rubber composition is applied onto less than 100% of the surface area of said fibers, and
wherein said rubberized, molded ballistic resistant fabric is produced by molding the fibrous layers together at a pressure of from about 200 psi to about 5000 psi.
