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.

在扫描型电子显微镜中进行单根碳纤维的纵向直接压缩试验，测定碳纤维的纵向压缩强度。两种类型的碳纤维，即中等和高拉伸强度碳纤维，用于测试。中等强度碳纤维的压缩强度和拉伸强度基本相同。相比之下，高强度碳纤维的压缩强度远低于拉伸强度。高抗拉强度碳纤维的低抗压强度可能是由高抗拉强度碳纤维制成的碳纤维增强塑料的低抗压强度的主要原因。
