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.
