摘要: 建立了缝纫单层板的有效弹性常数分析模型。通过考虑缝纫引起的铺层纤维的面内弯曲和非均匀分布,分析了缝纫参数(如缝纫行距、针距和缝线半径)对等效弹性常数的影响。结果表明,当缝纫方向垂直于铺层纤维方向时,随缝纫行距的减小或缝线半径的增大,纵向模量逐渐下降,而横向模量和剪切模量则逐渐提高;缝纫针距对纵向模量影响很小。

Abstract: A model for determining the effective elastic constants of stitched lamina is established, in which the effects of stitching parameters on elastic constants of stitched lamina are analyzed by considering the nonuniform distribution and in-plan waviness of fibers induced by stitching. The results show that, when the stitching direction is perpendicular to the fiber direction, the longitudinal modulus decreases but transverse modulus and shear modulus increase gradually with decreasing row spacing or increasing stitch thread radius.
