The fatigue test is conducted under tensile-tensile constant range loading. The test specimen is a cross-ply laminated CFRP (Carbon Fiber Reinforced Plastic) using a unidirectional fiber reinforced substrate and epoxy resin. The three carbon fibers adopted in this test are classified as high-strength, high-strain and high-strength/intermediate-elastic-modulus types. Fatigue damage in test specimens is quantified by an X-ray radiography penetrative crack detection method. The test results indicated that the fracture of all specimens occurred in sudden mode. The high-strength type CFRP should exhibit rupture in grip portion. The relationship between fatigue stress and number of cycles is approximately linear on a semi-logarithmic graph. After being subjected to 10(exp 7) stress cycles, the ratios of tensile fatigue strength to static tensile strength for high-strength, high-strain and high-strength/intermediate-elastic-modulus types CFRP were estimated to be 0.97, 0.85, and 0.76, respectively.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
