Composite fabrics combining high and low strength materials
Composite materials combining both high and low strength fibrous materials. More particularly, composite materials that are useful as lightweight vest covers for tactical vests and that are suitable for the formation of alternatives to conventional Modular Lightweight Load-carrying Equipment (MOLLE).
1. A vest or vest cover formed from a consolidated composite consisting essentially of:
a) a one-ply layer of a woven nylon fabric, said woven nylon fabric comprising fibers, wherein said fibers consist of warp nylon fibers having a tenacity of less than 10 g/denier and weft nylon fibers having a tenacity of less than 10 g/denier, said woven nylon fabric having a weave density of from about 25 warp fiber ends per inch to about 60 warp fiber ends per inch and from about 25 weft fiber ends per inch to about 60 weft fiber ends per inch; and
b) a two-ply non-woven fabric layer comprising two non-woven fiber plies, said non-woven fiber plies each comprising a plurality of unidirectionally oriented polyethylene fibers and each having an areal density of less than 100 g/m 2 ;
wherein the woven nylon fabric and the non-woven fabric layer are bonded together.
2. A vest or vest cover formed from a composite that consists essentially of:
a first fibrous material layer comprising one fibrous ply, said first fibrous material layer comprising fibers having a tenacity of less than 10 g/denier and wherein said fibers of said one fibrous ply are optionally embedded in a polymeric binder; and
a second fibrous material layer bonded to the first fibrous material layer, said second fibrous material layer comprising one or more fibrous plies, each of said one or more fibrous plies having an areal density of less than 100 g/m 2 , said second fibrous material comprising a plurality of multifilament fibers having a tenacity of greater than 10 g/denier and wherein said fibers of each ply are optionally embedded in a polymeric binder;
wherein said polymeric binder is present in one or both of said fibrous material layers; and
wherein the first fibrous material layer and the second fibrous material layer are directly bonded together with the present polymeric binder in either or both of said fibrous material layers as an adhesive.
3. A vest or vest cover formed from a composite that consists essentially of:
a first fibrous material layer comprising one fibrous ply, said first fibrous material layer comprising fibers having a tenacity of less than 10 g/denier and wherein said fibers of said one fibrous ply are optionally embedded in a polymeric binder; and
a second fibrous material layer bonded to the first fibrous material layer, said second fibrous material layer comprising one or more fibrous plies, each of said one or more fibrous plies having an areal density of less than 100 g/m 2 , said second fibrous material comprising a plurality of multifilament fibers having a tenacity of greater than 10 g/denier and wherein said fibers of each ply are optionally embedded in a polymeric binder;
wherein the first fibrous material layer and the second fibrous material layer are bonded together with an intermediate adhesive.
