후프 응력(hoop stress)에 대한 저항성이 개선된 박벽형 중공 관형 물품의 형성에 유용한 다중-플라이 하이브리드 복합 재료. 2개의 상이한 단일-플라이 프리프레그(pre-preg)는 결합제로 함침되고 층들의 섬유들이 서로에 대해 바이어스(bias)로 배향된 상태로 함께 라미네이팅된다. 하이브리드 복합재는 관형 물품으로 감기게 되는데, 이는 관형 물품의 전체 길이를 따라 탁월한 강도 균일성을 갖는다. Multi-ply, hybrid composite materials useful in the formation of thin walled, hollow, tubular articles having improved resistance to hoop stress. Two different, single-ply pre-pregs are impregnated with binders and laminated together with the fibers of the layers oriented at a bias relative to each other. The hybrid composite is rolled into a tubular article having excellent strength uniformity along the full length of the tubular article.
