10405 Internal Damage Behavior of the stitched CFRP Laminates Under Tensile Fatigue Loading

This study aims to conduct a fatigue simulation for predicting the stiffness degradation of thin-ply composite laminates with several ply thicknesses. For the simulation, a fatigue evolution model of intra-laminar damage in thin-ply composite laminates considering the effect of ply thickness was proposed. The intra-laminar damage evolution was modeled using the continuum damage mechanics model and the static and fatigue evolution law were formulated by relating the transverse crack density to the damage variable. The finite element simulation using the proposed model was conducted to predict the stiffness degradation of the laminates as a function of the number of loading cycles. The simulation results show that the experimental data can be reproduced by using the proposed fatigue model.

The Impact

The goals of this paper are to identify the impact damage behavior of plain-weave E-glass/epoxy composites and predict the fatigue life of the composites with impact-induced damage under constant amplitude loading. To identify these behaviors, the low velocity impact and fatigue after impact tests are performed for glass/epoxy composites having two types of fiber orientations. The impact damage behavior is dependent on the fiber orientation of the composites. The fatigue life of the impacted composites can be identified through the prediction model, which was proposed on the carbon/epoxy laminates by authors regardless of fiber orientations.

It is the purpose of this study to investigate the effects of fatigue loading on two variations of hybrid composite tubes. The two types of samples are both composed of AS-4D/carbon fibers and e-glass fibers. The key distinctions between the two samples being the orientation and the number of layers. The samples were composed of the following orientations [90/20/90/20/90/20/20/90/20] and [90/90/20/90/20/20/90/20]. The experiment is designed to not only compare the two samples, but to develop some experimental data for a fatigue curve for similar materials. All loading for this experiment takes place in a controlled environment. Both temperature and the specific gravity of the water are measured and controlled.
