查询词典 effective diameter of thread

The in-plane equivalent elastic modulus and tensile strength of stitched composite laminates are studied, and its found that the in-plane equivalent elastic modulus decreases with the increase of stitch density, stitch thread diameter, maximal misalignment angle and the distortion width, and the range is about 5%. The tensile strength of stitched composite laminate increases with the increase of stitch step and decreases with the stitch space.

研究结果表明：随着缝纫密度、缝纫线直径、最大纤维偏转角和缝纫变形区宽度的增加，缝纫复合材料层合板面内等效模量逐渐降低，最大降幅一般在5%左右；缝纫复合材料层合板的拉伸强度随缝纫针距的增加而增大，随缝纫行距的增加而降低，因此缝纫密度对拉伸强度的影响程度要看具体的缝纫针距和行距。
