States of interlaminar and fiber/resin interface were observed after the bending fatigue test. Interlaminar fracture toughness and interfacial shear strength between fiber and resin were measured by ENF (End Notched Flexure) test and micro droplet test, respectively. To discuss the behavior of matrix crack propagations around reinforcing carbon fiber, the probability for connecting two matrix cracks initiated in the both sides of model specimen was measured after critical failure, when the molecular weight of the matrix was changed. The bending fatigue property was improved by increasing the molecular weight of the thermoplastic epoxy matrix. It was found that the interlaminar fracture toughness was improved by increasing the weight average molecular weight of the matrix, and the state of fracture surface was varied depending on the condition of weight average molecular weight of the matrix. Interfacial strength between fiber and matrix was also improved, when the weight average molecular weight of the matrix was elevated. The probability for connecting two off-set matrix cracks in the model specimen was reduced according to the elevation of molecular weight. It was found that the crack propagation along the interfacial between fiber and matrix was prevented due to the increase of interfacial shear strength, when the weight average molecular weight of the matrix was elevated.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1_description_25":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14988/pa.2017.0000016909","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_15":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"同志社大学ハリス理化学研究所","subitem_publisher_language":"ja"}]},"item_1_publisher_16":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Harris
