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.
