Note (General): 国際共同研究VAMAS(Versailles project on Advanced Materials and Standards)における研究課題「高分子複合材料」ではFRPの引張疲れ試験法評価に関する第1次共同実験が行われた。共通試料として1方向繊維強化エポキシ樹脂複合材料(GFRPおよびCFRP)の短冊平板が参加機関にそれぞれ提供された。評価は同材料の繊維方向について正弦波形による繰り返し引張荷重疲れ試験を実施し、標準試験方法確立のための検討資料を得るものであった。ここでは同評価試験の結果、および同成果を踏まえて1方向強化CFRPについて独自に行った試験片形状などの比較検討結果を報告する。
The aim of the Versailles Project on Advanced Materials and Standards (VAMAS) program is to evaluate the mechanical properties of advanced materials. In this study, as a part of the polymer composites, the first phase of this round robin test was carried out to examine the tension-tension fatigue properties of unidirectional Glass Fiber Reinforced Plastics (GFRP) and Carbon Fiber Reinforced Plastics (CFRP). Fatigue tests were undertaken in a sinusoidal load-controlled testing mode, with a load ratio of 0.1. In the case of CFRP tests, the comparison of cold-setting epoxy resin and curing epoxy resin film as the end-tab adhesive was made. It was found that the fatigue strength differed largely between the two types of tab adhesive. In another study, the effects of the end-tab configuration of the specimen and the testing frequency of fatigue behavior of unidirectional CFRP specimen were examined. As for the tab configuration, 10 deg tapered and untapered end-tab specimens were provided. On the testing frequency, fatigue tests were conducted with 2, 5 and 10 Hz. The difference of fatigue strength under these testing conditions was found to be small in the present study.
