摘要: 针对簇绒缝合工艺制备的碳纤维三维预制体在高温处理后易产生缝线脱出的问题,开发了一种新型单边缝合技术——“铆接缝合”技术,其缝合线称为全线铆钉。本文采用二维编织技术制备了全线铆钉,通过单边铆接缝合技术制备了三维织物预制体,主要研究了铆钉参数及高温处理对全线铆钉抽拔性能的影响。研究结果表明:全线铆钉抽拔强力随着铆钉编织节距的增加呈现出先增大后减小的趋势;铆钉编织股数的增加使全线铆钉抽拔强力表现出指数增长的特性;铆接预制体经300~600 ℃高温处理1 h后,全线铆钉抽拔强力由25.79 N降低至2.96 N,且性能衰减速度随着温度升高而减小;在600 ℃处理条件下,全线铆钉抽拔强力较簇绒缝合提高约7倍。

Abstract: Based on the issue of stitching thread pullout in carbon fiber three-dimensional preforms prepared using tufting processes after high-temperature treatment, a novel unilateral stitching technique-“riveting”-has been developed, with the stitching line referred to as a full-line rivet (FLR). In this study, a two-dimensional braiding technique was used to fabricate the FLR, and a three-dimensional fabric preform was created using the unilateral riveting technique. The research primarily focuses on the effects of FLR parameters and high-temperature treatment on the pullout performance of FLR. The results show that the pullout strength of FLR increases initially and then decreases as FLR weaving pitch increases. The pullout strength of FLR exhibits an exponential growth pattern with the increase in the number of woven strands. After the riveted preform undergoes high temperature treatment at 300~600 ℃ for 1 h, the pullout strength of FLR decreases from 25.79 N to 2.96 N, and the rate of performance degradation slows down as the temperature increases. Under the 600 ℃ treatment condition, the pullout strength of FLR is approximately 7 times higher than that of tufting.
