摘要/Abstract

摘要： 采用碳纤维增强复合材料管件代替传统的金属材质的吸能盒,实现了在提高能量吸收能力的同时减轻车身重量。管件的增强体分别是经过缝纫增强的碳纤维编织物和未经过缝纫增强的碳纤维编织物,选用环氧树脂作为基体材料运用真空辅助成型工艺完成整个管件的制作。对有无缝纫增强形式对碳纤维编织物增强复合材料管件物能量吸收能力的影响展开研究。研究结果表明,经过缝纫增强的碳纤维编织管件能够明显提高管件的能量吸收能力,经过缝纫增强的管件的比能量吸收值比未经缝纫增强的高出16%。为了研究管件的能量吸收机理,对测试后的管件进行了树脂包埋、抛光和观察,观察后发现经过缝纫编织的管件物的中央裂纹受到了缝纫结构的限制,使得中央裂纹不易扩展,能量吸收性能得到明显的提高。

Abstract: In this study, two kinds of carbon fiber braiding fabric including with and without stitching structure as reinforcement, epoxy resin as matrix were chosen to manufacture carbon fiber braiding composite tubes via transfer molding (RTM) method. The effects of stitching on energy absorption property and mechanical property of braiding composite tubes were investigated. To investigate the energy absorption property and mechanic property of these two kinds of braiding composite tubes, quasi-static compression tests were performed. It was found that stitching improved the energy absorption capacity and mechanical properties obviously. The specific energy absorption of the tube with stitch was 16% higher than the one without stitch. To research the energy absorption mechanisms, the tested tubes were cast in resin, cut, and polished in order to document the energy absorption mechanisms. It was found that the central crack was restrained by the stitching yarn in the stitched braided FRP tube during the crushing process. That is to say, the mechanical property in the thickness of braided tube composite was enhanced. With the effect control of the central crack by the stitching yarn, high energy absorption management could be obtained.

Key words: composite tubes, energy absorption, stitch reinforcement, braiding
