    Abstract: A process for forming defect-free fibrous composite materials. More particularly, a process for forming blister-free fibrous composites without having to actively monitor or control blister formation during molding of a stack of plies, and to blister-free composite materials fabricated therefrom. Fibrous plies are coated with a dry, particulate binder without impregnating the plies with the binder. Gaps between fibers/tapes allow air to diffuse out of the stack without affecting the binder coating, thereby avoiding blister formation.

    Abstract translation: 一种形成无缺陷纤维复合材料的方法。 更具体地说,提供一种形成无泡的纤维复合材料的方法,而不必积极地监控或控制层叠堆叠体的模塑过程中的气泡形成,并涉及由其制造的无气泡复合材料。 纤维层用干燥的微粒粘合剂涂布,而不用粘合剂浸渍层。 纤维/胶带之间的间隙可以让空气扩散出叠层,而不会影响粘合剂涂层,从而避免起泡现象。

    Abstract: 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.
