RESEARCH ON THE TECHNOLOGY OF SINGLE-SIDED TWO NEEDLES STITCHING EQUIPMENT FOR COMPOSITES PREFORM
摘要
Abstract
Stitching technique can effectively improve inter-laminar strength of composite materials and their damage tolerance.The integral structure can be prepared by the stitching joint.Based on the working principle of industrial sewing machine.We established two needles stroke relationship through researching the cooperative relationship between a conventional needle and a catcher-needle in the process of forming coil.And we designed the camcrank link mechanism to realize the two needles cooperation movement.The single-sided two needles stitching head and three axis linkage platform are combined to stitch preform.We explored the effect of the angle between the two needles on coil forming.The study shows that it can form the coil probability up to 90％ when the angle between the two needles is 45° to 60°.It makes the probability of the formation of the coil reduced when the angle between the two needles is too large or small.The experiment verified the rationality of the structural design of the single-side two needles stitching equipment.This paper provides a theoretical basis for the optimization of the equipment.关键词
