Abstract:
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 mecha-nism, 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.
