全线铆钉的制备与抽拔性能研究
Study on preparation and pullout performance of full-line rivets
摘要
Abstract
Based on the issue of stitching thread pullout in carbon fiber three-dimensional preforms prepared u-sing 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 de-creases 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 degra-dation 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.关键词
