Abstract:
A flexible laminated high strength, tear resistant, gas impermeable, ultra-violet radiation and wind resistant material for lighter-than-air vehicles and the like, comprising:a) a flexible wall having interior and exterior exposed surfaces and including multiple bonded layers intermediate of said interior and exterior exposed surfaces;b) said interior exposed surface having a first layer of bonding resin;c) at least one first layer of high strength woven material having individual strands at 0.degree. and 90.degree. bonded to said first layer of bonding resin;d) at least one second layer of high strength woven material having individual strands at plus and minus 45.degree.;e) securing means for bonding said at least one first and said at least one second layers together;f) said at least one second layer having a strain-at failure value greater than said at least one first layer;g) a second layer of bonding resin;h) a layer of gas impermeable plastic resin material;i) said second layer of bonding resin bonding said layer of gas impermeable plastic resin material to said at least one second layer of high strength woven material;j) a layer of ultra-violet radiation and wind resistant material;k) a third layer of said bonding resin;l) said third layer of said bonding resin bonding said layer of ultra-violet radiation and wind resistant material to said impermeable plastic resin material;m) said exterior exposed surface being a fourth layer of bonding resin;n) said fourth layer of said bonding resin having bonded to said ultra-violet radiation and wind resistant material.
