| Research Abstract |
Longitudinal direct compression testing of a single carbon fiber was performed in a scanning electron microscope, and the longitudinal compressive strength of a carbon fiber was measured. Two types of carbon fiber, i.e. intermediate and high tensile strength carbon fibers, were used for the test. The compressive and tensile strengths of the intermediate tensile strength carbon fiber were almost the same. In contrast, the compressive strength of the high strength carbon fiber was much lower than the tensile strength. The low compressive strength of high tensile strength carbon fiber could be the main cause of low compressive strength of a carbon fiber reinforced plastic made of a high tensile strength carbon fiber.
