缝合复合材料层板三维纤维弯曲模型及压缩强度预报

In-plane local fiber waviness model of stitched laminates is presented under the assumption that the cross section of extruded stitch gets elliptical.

提出了缝合层板面内局部纤维弯曲模型,假设缝合线受挤压后横截面为椭圆形,指出当纤维弯曲幅度较小时,缝合仅造成单胞内局部纤维弯曲,纤维弯曲角为特定值,由纤维种类决定;当纤维弯曲幅度较大时,缝合造成单胞内整体纤维弯曲,纤维弯曲角大于特定值,由纤维弯曲幅度和单胞尺寸决定。

The shape of stitch holes affects fiber waviness.

提出了缝合复合材料层板的刚度预报模型,该模型考虑了缝合针脚处的孔洞对刚度的影响,描述了缝合孔洞的几何形态,建立了孔洞形态与纤维弯曲的关系,采用平均刚度法和经典层合板理论进行了刚度预报,获得了与试验数据相吻合的预报结果,表明了该模型的有效性,详细探讨了缝合孔洞对缝合层板刚度的影响规律,得到一些有益结论。
