Tredimensjonal forsterket cellul¶r matrikskompositt og fremgangsmåte for fremstilling av samme

摘要

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.
