Abstract
A composite having a first layer and a second layer. The first layer is a nonwoven layer containing high modulus fibers having a modulus of at least 8 GPa and thermoplastic binder fibers, where at least a portion of the high modulus fibers are connected to the binder fibers, and where the first layer has a solidity of between about 10 and 90%. The second layer is a textile layer selected from the group consisting of a knit layer, a woven layer, bidirectional laminates, and a unidirectional layer. The second layer contains high modulus fibers having a modulus of at least 8 GPa in a thermoplastic matrix.
Claims22
A composite comprising:
- a first layer having an upper surface and a lower surface, wherein the first layer is a nonwoven layer comprising high modulus fibers having a modulus of at least 8 GPa and thermoplastic binder fibers, wherein at least a portion of the high modulus fibers are connected to the binder fibers, and wherein the first layer has a solidity of between about 10 and 90%;
- and,
- a second layer on the upper surface of the first layer, wherein the second layer is a textile layer selected from the group consisting of a knit layer, a woven layer, bidirectional laminates, and a unidirectional layer, wherein the second layer comprises high modulus fibers having a modulus of at least 8 GPa in a thermoplastic matrix.
A composite comprising:
