Abstract
This invention relates to a fire resistant multilayer complex ballistic resistant article comprising at least one first layer comprised a plurality of flammable fibers a first matrix and at least one second layer which is adjacent to said first layer which comprises a plurality of fire resistant fibers in a second matrix, wherein the second matrix comprises a fire retardant material and is different from the first matrix material.
Claims31
A fire resistant complex multilayer ballistic resistant article comprising a plurality of alternating first and second plies, wherein said first ply comprises one or more first layers comprising a network of flammable polymeric fibers in a first matrix, said fibers having a tenacity of at least about 7 g/denier, a tensile modulus of at least about 160 g/denier and an energy-to-break of at least about 8 joules/grams;
- and said second ply comprises one or more second layers comprising a network of fire resistant organic or inorganic fibers in a second matrix material wherein said second matrix material is a fire retardant material and is different from said first matrix material.
A fire resistant complex multilayer ballistic resistant article comprising alternating first and second plies wherein said first ply comprises one or more first layers each of said layers comprising a network of polyethylene fibers having a tenacity of at least about 7 g/denier, a tensile modulus of at least about 160 g/denier and an energy-to-break of at least about 8 joules/grams dispersed in a polymeric matrix, said first layer comprises two or more sheet-like fiber arrays in which said fibers are arranged substantially parallel to one another along a common fiber direction wherein adjacent arrays are aligned at an angle with respect to the longitudinal axis of the parallel fibers contained in said adjacent array, and said second ply comprising one or more second layers comprising a network of glass fibers in a fire retardant matrix material.
