编织复合材料预制体铺覆成型的数值模拟

摘要
针对平面编织复合材料预制体在曲面铺覆过程中的局部变形,建立了三维有限元模型,利用商业有限元软件Abaqus模拟了预制体在铺覆成型过程中的纤维束变形规律。研究了0°和45°碳纤维织物在球面铺覆过程的变形过程和局部剪切变形。结果表明,纤维束之间的滑动和纤维束起皱是该预制体在球面铺覆过程中的典型变形模式。在0°织物的球形铺覆变形中,0°和90°纤维束的剪切变形角最小,45°方向纤维束的剪切变形角最大;在45°织物的铺覆变形中,0°和90°纤维束的剪切变形角最大,45°方向纤维束的剪切变形角最小。
In this paper, a three-dimensional finite element model is established for the local deformation of the woven composite preforms during the draping. The commercial finite element software Abaqus is employed to predict the deformation of the carbon fiber preform in a spherical draping. The deformation process of the 0° and 45° carbon fabrics in the spherical draping process is studied. The results show that sliding between fibers and wrinkling of fibers are the typical deformation modes of the preform during the spherical draping. In the spherical draping deformation of0° fabric,the shear deformation angle of the 0° and 90° fiber bundles is the smallest,and the shear deformation angle of the fiber bundle is the largest in the 45° direction; for the 45° fabric,the shear deformation angles of the 0° and90° fiber bundles are the largest, and that of the fiber bundle in the 45° direction is the smallest.
