Abstract
An inflatable safety product may include a fabric or flexible composite material. The fabric or flexible composite material includes a low weight, high strength substrate. In certain embodiments, the fabric or flexible composite material has a tensile strength of at least 190 lbs/in and/or a tear strength of at least 13 lbs/in and/or a radiant heat resistance of at least 180 seconds, and a substrate weight of less than or equal to 3 ounces/yd2.
Claims16
A fabric or flexible composite material for an inflatable safety product, the fabric or flexible composite material comprising a low weight, high strength substrate comprising a plurality of ultra-high molecular weight polyethylene fibers, wherein the substrate comprises a weight of 1 ounces/yd2, wherein the fabric or flexible composite material comprises a tensile strength of at least 190 lbs/in and a tear strength of at least 13 lbs/in and a weight of the fabric or flexible composite material less than or equal to 4 ounces/yd2.
A fabric or flexible composite material for an inflatable safety product, the fabric or flexible composite material comprising a low weight, high strength substrate comprising a plurality of fibers, wherein a material of the plurality of fibers comprises a melting temperature less than 400° F., wherein the substrate comprises a weight of less than or equal to 1 ounces/yd2, wherein a weight of the fabric or flexible composite material is less than or equal to 4 ounces/yd2, and wherein the fabric or flexible composite material comprises tensile strength of at least 190 lbs/in.
A fabric or flexible composite material for an inflatable safety product, the fabric or flexible composite material comprising:
- a low weight, high strength substrate comprising a tear strength of at least 13 lbs/in and a substrate weight of less than or equal to 1 ounces/yd2, wherein the low weight, high strength substrate comprises an inner surface and an outer surface;
- a continuous metallic layer extending over at least a portion of the outer surface of the low weight, high strength substrate;
- and
- an intermediate layer between the continuous metallic layer and the low weight, high strength substrate, wherein the intermediate layer adheres the continuous metallic layer to the outer surface.
A fabric or flexible composite material for an inflatable safety product, the fabric or flexible composite material comprising:
- a low weight, high strength substrate comprising at least one surface;
- and
- a metallic layer on the at least one surface of the low weight, high strength substrate, wherein the metallic layer is provided as a discrete pattern on the at least one surface, the discrete pattern defining a plurality of covered portions on the at least one surface and a plurality of uncovered portions on the at least one surface, and wherein the plurality of connected portions are connected with each other;
- and
- a substrate weight of less than or equal to 1 ounces/yd2, wherein the fabric or flexible composite material comprises a radiant heat resistance of at least 180 seconds, when exposed to radiant heat flux of 1.5 Btu/ft2-sec or greater, for at least 180 seconds.
