报告摘要：Over the last three decades, Liquid Composite Molding (LCM) and Prepregs thermoforming are recognized more and more by industries to produce the big, thick, light and strong advanced composite parts. As the first stage in LCM and the principal stage in prepregs thermoforming processes, the textile reinforcements forming plays an important role during the composites manufacturing. The forming may be difficult to control and can lead to the defects when the parts have the high curvatures and large deformations. Once the forming defects are created, they cannot be removed or modified in the following manufacturing steps and consequently stay in the final composite parts. In order to manufacture the advanced composites without defects, the first study should be addressed to the first step or the principal step of the whole manufacturing process. On the other hand, good knowledge of the mechanical properties of the textile reinforcements is necessary to optimize the composite manufacturing process, in particular for the textile reinforcements with the advanced structure. The present work concerns at first the investigation of the multiscale characterisation of mechanical properties of the new/developed textile composites, especially the influence of the structural and processing parameters. In order to improve the quality of the textile composites, the feasibility forming conditions of their reinforcements will be studied through the experimental and numerical simulation approaches.
