Abstract
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.
