초록 (요약문)
In this paper, the static cyclic mechanical behavior of fiber reinforced thermoplastic (FRP) is investigated by means of tensile static and fatigue tests, scanning electron microscope image analysis, and finite element simulations. In the investigation, the effect of the temperature of the heat chamber on mechanical properties of the FRP, for 100 oC, 60 oC, and 40 oC temperature of the heat chamber, and the fiber direction of 0o, 45o and 90o from injection direction have been accounted for. For the modeling of the failure of the components in the heat chamber, a damage model has been utilized for the FRP, respectively. The considered damage model and failure criteria have been included in a FE simulation model implemented in Abaqus/Explicit and showed good accuracy in predicting the progressive failure of the FRP structure under uniaxial tensile and bending loading conditions. In order to accurately predict the effects of various temperatures and fiber orientation direction on the mechanical properties of the fiber reinforced thermoplastic
