STUDY ON TENSION-TENSION FATIGUE PERFORMANCE FOR CARBON/GLASSHYBRIDIZED FABRIC REINFORCED COMPOSITES

Abstract

Abstract: Fiber hybridization is an effective solution to achieve a completive material with balanced price and properties. Glass/carbon hybridized fabric (GCHF) is the typical example. Fatigue performance is one of the key material parameters of composites for engineering applications. In this paper, the material for spar caps manufacturing of wind blade were used as research subject. Four different carbon ratio uni-directional GCHF were chosen to make hybrid composites, and both static and fatigue test (R=0.1) were carried out. Moreover, pure glass and pure carbon were also tested for comparison. It was demonstrated that high-cycle fatigue of GCHF reinforced composites correspond to the linear rule of mixtures well, but low-cycle fatigue is relatively worse. Based on the experimental study, a fast way of GCHF reinforced composites fatigue properties prediction has been achieved.
