In this study, effects of different stitching parameters on formability behaviour of multi-layerd para-armide panels were investigated. Different stitching pattern namely, Uni-axial longitudinal, Bi-axial straight, Uni-axial-diagonal, Bi-axial-diagonal, Edge stitch and Unstitched were used for binding different layers. Stitch length and gap parameters were also considered while formability using different values. Diamond quilted stitched with less stitch gap and short stitch length shows severe surface wrinkling and stitch thread breakage, whereas unstitched layers show a better deformability without wrinkling and stitch thread breakage. Similarly, diamond quilted stitched shows a very less drawing-in values both in warp and weft directions. As stitch density increases, the drawing-in measurement value reduced due the formation of more rigid layer to resist the deformation. Unstitch and diamond quilted preform possess the highest and least deformation recovery percentage respectivly. Moreover, deformation recovery percentage of the layers become very less as the stich gap and stitch length reduced.

在这项研究中，研究了不同的缝合参数对多层对位臂板的可成形性行为的影响。使用不同的针迹样式（即单轴纵向，双轴笔直，单轴对角线，双轴对角线，边缘针迹和未缝线）来装订不同的层。在使用不同值的可成形性时，还应考虑针迹长度和间隙参数。缝制较少缝隙且针迹长度较短的金刚石缝针迹显示出严重的表面起皱和缝线断裂，而未缝制的层显示出更好的可变形性，而没有起皱和缝线断裂。同样，缝制的钻石diamond缝在经纱和纬纱方向上的穿入值都非常小。随着针迹密度的增加，由于形成了更大的刚性层以抵抗变形，因此缩进测量值降低了。未缝合和金刚石缝的预成型坯分别具有最高和最低的变形回复率。而且，随着缝隙和针迹长度的减小，层的变形恢复百分比变得非常小。
