摘要：

In filament winding, both the tension applied to the fiber strands and the subsequent cure schedule are important manufacturing variables that produce residual stresses and strains. A "radial cut method" was used to determine the circumferential and radial residual stress profiles in S2-glass fiber/epoxy and E/XA-A carbon fiber/epoxy circumferentially-wound composite rings. Of particular interest in this study were radially-thick composite rings in which the effect of cure schedules as well as constant and variable winding tension profiles on the radial residual stress profiles were evaluated. Several design-oriented relationships for estimating the maximum radial residual stress were developed.
