Abstract
Composite tubes consisting of continuous glass fibers with five distinct combinations of commercially available sizings and flexible polyurethane matrices were wet-filament wound and tested to determine the effect of the different material combinations on the uniaxial tensile response of the tubes. Significant differences in strength and elongation of hoop-wound tubes were observed. Lower levels of fiber-matrix adhesion, as observed on failure surfaces with a scanning electron microscope, correlated with higher elongation perpendicular to the fibers. Tubes wound with quasi-isotropic layups consisting of (0/±60) and (90/±30) sublaminates were also studied. Only one material system was used for the quasi-isotropic tubes. The two quasi-isotropic laminates had surprisingly different stress-strain curves due to fiber-tension-controlled behavior in the first case and matrix-controlled behavior in the second case. Fiber buckling in the soft polyurethane matrices played an important role in the stress-strain behavior of many of tubes investigated.
