EVALUATION OF FATIGUE BEHAVIOR ON CARBON FIBER/EPOXY COMPOSITE LAMINATES AT ROOM TEMPERATURE
Journal Title: Jurnalul Stiintific TURBO - Year 2018, Vol 5, Issue 2
Abstract
Investigation of low-cycle fatigue of composites is of vital importance for the design of structural components. In this study, Low cycle fatigue behaviour of a CFR epoxy composite was investigated under sinusoidal wave loading at constant amplitude, a frequency of 8 Hz and stress ration R of 0.1. Furthermore, present study experimental results were ploted on S-N diagram and compared with relevant literature data, showing an incresed in fatigue resistance. It is found that the reinforcement architecture of the composite material has an important influence on the fatigue life performances, when two materials are tested in the same conditions. Likewise, it was found that an increase in apllied frequency can lead to lower fatigue life since energy dissipated in the laminate cause heating that can reach the glass transition temperature Tg, inducing structural degradation.
