Abstract
An investigation was made on relationship between a flexural fatigue test and test specimen shapes of carbon fiber reinforced plastic (CFRP). Five kinds of material were tested including carbon fibers with medium strength, high ductility, and high strength, cross-ply laminates as pre-preg base materials using epoxy resin for raw material, and pseudo isotropic laminates. Static bending test and flexural fatigue test were carried out for dynamic characteristics to derive the relationship (S-N line) between iterative bending stress and the number of repetition before breakdown. Comparison of the test results arrived at the following conclusions: The high-ductility and high-strength laminates exhibited significant difference in the S-N inclination, which is because of local compression breakdown at edges of the laminates; the flexural fatigue strength is compared in a descending order as the medium-strength laminates, high-ductility laminates, high-strength laminates, high-strength pseudo isotropic laminates, and medium-strength fabric laminates. The static bending strength was in the order of the high-strength laminates, high-ductility laminates, high-strength pseudo isotropic laminates, and medium-strength fabric laminates. 12 refs., 16 figs., 2 tabs.
