Performance improved prestressed pipe and hollow member where the additional exterior layer of circumferential wound fiber and thermoset polymer on a cured fiber reinforced composite pipe and hollow member creates compression stresses in the cured pipe and hollow member to offset the tension stresses due to operational temperature loadings. In its preferred embodiment this performance improved prestressed pipe and hollow member makes composite piping for rocket engines practical.

[ What is claimed is:] [1.]1. A prestressed composite pipe comprisinga first inner component comprising a high-modulus fiber reinforced polymer-matrix composite, generally tubular, cylindrical pipe and hollow member, anda second outer component comprising at least one circumferential winding of high modulus fiber possessing a prestress tension, said winding secured to said first component by polymer attachment means,wherein said prestress tension of said circumferential winding is selected for compression stress creation in said first cured polymer matrix component disposed for the balance, offset, and nullification of non-elastic tension stresses due to operational loadings.
