 note = {本研究は、AS-4/PEEK熱可塑性複合材料の面圧静強度や面圧疲労強度および円孔まわりに生じる損傷の状況を明らかにするため、室温環境条件下でピン継手試験片による面圧静試験と面圧疲労試験を実施した。試験項目としては、静試験により荷重と円孔変形の関係および面圧静試験を調べた。また、疲労試験によって円孔変形と荷重繰返し数の関係、疲労寿命、および面圧残存強度などを求め、寿命に及ぼす負荷速度の影響も調べた。静・疲労試験の前後では、超音波Cスキャン検査、1部については軟X線検査を実施し、円孔まわりにおける損傷の進行を調べた。また、試験後に円孔断面を板厚方向に切り出し、電界放射形走査電子顕微鏡によって、円孔まわりの損傷の様子を観察した。同時に、得られた試験結果について解析し検討した。, The objective of this study was to investigate static and fatigue strengths and damage around the hole of pin-joint specimens of an AS-4/PEEK thermoplastic material. Both static and fatigue tests were conducted at room temperature. Static tests clarified the relationship between load and deformation of a pin-joint hole and bearing strength. Fatigue tests clarified the relationships of load cycles and deformation of a pin-joint hole, S-N (Stress and Number of cycle) relationships, residual bearing strength, and the influence of the load cycle rate on fatigue life. Before and after static and fatigue tests, the edges around pin-joint holes were non destructively tested by using an ultrasonic type C scan technology and a soft X-ray method to investigate damage growth. After fatigue and static tests, some specimens were sectioned and damage in the vicinity of the hole edge was observed by using a field emmission-type scanning electron microscope., 資料番号: AA0004229000, レポート番号: NAL TR-1214},
