摘要

铆接是碳纤维增强聚合物基复合材料（CFRP）的一种重要连接方法，但是传统铆接极易导致CFRP 接头出现过大的干涉量和严重的损伤，造成质量隐患。本文通过试验方式对CFRP 试件开展了纯铆接、垫圈铆接、衬套铆接和垫圈+ 衬套铆接的损伤行为研究。结果表明，纯铆接接头的平均干涉量最大（远大于2%），且接头截面损伤最严重；垫圈铆接接头的平均干涉量为0.757%，接头截面几乎没有损伤；衬套铆接接头的平均干涉量为0.956%，但是镦头歪斜对孔周造成了挤压变形等损伤；垫圈+衬套铆接接头的平均干涉量为–0.915%，没有形成有效干涉，接头截面未见明显损伤。

Abstract

Riveting is an important connection method for carbon fiber reinforced polymer (CFRP) composites

however

traditional riveting is highly susceptible to causing excessive interference and severe damage to CFRP joints

leading to potential quality hazards. This study experimentally investigated the damage behavior of CFRP specimens subjected to various riveting methods

including straight riveting

washer riveting

chuck bushing riveting

and washer-chuck bushing riveting. The results indicate that the average interference of straight riveted joints is the highest

substantially greater than 2%

with joints exhibiting the most severe cross-sectional damage. In contrast

joints riveted with washers show an average interference of 0.757% with virtually no damage to the joints’ cross-section. Joints riveted with chuck bushings are of an average interference of 0.956%

but the tilt of rivet head causes compressive deformation and other damages around the hole. The combination of washer and chuck bushing riveting results in an average interference of –0.915%

without forming effective interference and observing no tangible damage on the joints’ cross-section.
