The aim of this study is to investigate characteristics of fatigue damage of CFRP modified with
MFC by TDA under tensile cyclic loading. In this paper, fatigue life of CFRP modified with MFC was
investigated under cyclic loading. Characteristics of fatigue damage of CFRP modified with MFC were
evaluated by thermo-elastic damage analysis. Maximum improvement in fatigue life was also obtained
under cyclic loading when epoxy matrix was enhanced with 0.3wt% of MFC as well as under static
loading. Result of TDA showed same tendency as the result of fatigue test, and the result of TDA well
expressed the fatigue damage behavior of plain woven CFRP plate. Eventually, TDA was effective for
clear understanding the degree of fatigue damage progression of CFRP modified with MFC.
