Abstract
A light-weight and impact-resistant composite material formed from a three-dimensional textile structure preform comprising at least three systems of yarns that define a plurality of interstices within the textile structure. A cellular matrix material impregnates the textile structure so as to fill the interstices of the three-dimensional textile structure and to coat at least a portion of the surface area thereof.
Claims11
A lightweight and impact resistant composite material comprising:
- (a) a substantially non-compressible uni-layer three-dimensional textile structure preform formed of at least three mutually perpendicular systems of yarns that define a plurality of interstices within said textile structure;
- and
- (b) a cellular matrix material that substantially fills the interstices of said three-dimensional textile structure and serves to create voids therein.
