摘　　要：纤维增强树脂基复合材料具有高比强度和高比刚度等优异特性,被广泛应用于汽车领域以实现汽车轻量化。然而,纤维织物的多尺度特性使其在复杂形状的车身零部件成型中变形机制十分复杂,极易产生成型缺陷,削弱成型后的复合材料力学性能。表征织物变形特性,揭示织物变形机制,是准确预测织物复杂形状成型,指导织物成型工艺参数合理设计的重要基础。因此,本文针对织物在成型过程中的压缩、剪切、弯曲和滑移4种关键变形特性及在复杂几何形状中成型特性的研究进展进行综述,详细介绍了织物上述变形和成型特性的研究方法及研究热点。本文将为织物的变形机制研究、复杂形状成型精准预测和工艺参数合理设计提供指导,推动复合材料在汽车领域中的大规模应用。Fiber reinforced composites are broadly used in the vehicle industry to realize the lightweight of automobile,due to its excellent performances such as high specific strength and stiffness.However,the multiscale nature of fabric results in the extremely complicated deformation mechanism of fabric in the forming of automobile component with complex shape.Characterization of fabric deformation behavior and revealing the fabric deformation mechanism,is the foundation that accurately predicts the fabric forming in the complex shape and guides the reasonable design of process parameters.Therefore,in this paper,four key deformation modes of fabric in the forming including compaction,shearing,bending and sliding are reviewed.In addition,the draping behavior in the complex shape forming is also reviewed.The research methods and focuses of deformation and draping behavior are introduced in detail.This paper will provide guidance for the research of fabric deformation mechanism,accurate prediction of fabric in complex shape forming,and the reasonable design of process parameters.These will promote the large-scale application of composites in the automotive field.
