Abstract:

In order to satisfy the market needs to different kinds of 3-D woven fabric, and improve the adaptability of the multi-rapier loom for products, the paper proposed a novel modeling process named silvage modeling for weaving 3-D woven fabric on the molti-rapier loom, based on the analysis on the existed advantages and disadvantages of various modeling processes. Combining with the need of the novel process, this paper improved the structural design of the selvage and beating-up system in current multi-rapier loom. Meanwhile, it simply introduced the weaving process of the novel process. By weaving cylinder replition fabric on a small sample loom, a cylinder repletion fabric was woven according to the selvage modeling process. The results show that the application of the salvage modeling process in weaving composite preform can improve the adaptability of the loom to more fabric product types to a certain extent. In addition, it can solve the problem that  the loom couldn't weave large-wall thickness hollow woven fabric due to the restructions of the layer number.
