摘要

摘要本研究的目的是研究湿热老化和热老化对相似和不同试样粘接接头的影响。重点研究了铝/铝、CFRP/CFRP相似键合、铝/CFRP不同键合的单搭接结构。了解这些节点随着时间的推移和最终失效的行为可以提高它们在结构中的耐久性、可靠性和安全性。研究将SLJ试件置于53℃的自来水中浸泡20天，进行湿热老化试验，并将另一组接头置于相同温度的烤箱中进行热老化试验。该研究评估了未老化、湿热老化和热老化样品的强度，并通过三点弯曲试验进行了测试。使用最近设计的夹具测试了各种负载水平，包括70%，60%和50%的静态负载水平。结果表明:铝/铝slj接头强度最高，热、湿热时效后接头强度降低;失效模式和导致失效的循环次数也随载荷百分比和老化而变化。最终，该研究旨在评估和对比经历不同老化过程的样品的强度。关键词:关节静力与疲劳强度湿热与热条件弯曲载荷。中铁十九局有限公司科技研究计划(批准号2021- b03)。披露声明作者未报告潜在的利益冲突。中国辽宁省“兴辽英才计划”青年拔尖人才资助项目(No.XLYC2007146)。

An experimental investigation of static and fatigue behavior of various adhesive single lap joints under bending loads subjected to hygrothermal and thermal conditions

ABSTRACTThe objective of this study is to investigate the impact of hygrothermal and thermal aging on adhesive bonding joints of similar and dissimilar specimens. The research focuses on the single lap joint (SLJ) configuration using Aluminum/Aluminum and CFRP/CFRP for similar bonding and Aluminum/CFRP for dissimilar bonding. Understanding the behavior of such joints over time and eventual failure can enhance their durability, reliability, and safety in structures. The study submerged SLJ specimens in tap water at a temperature of 53°C for 20 days to assess hygrothermal aging and kept another group of joints in an oven set at the same temperature for thermal aging. The research evaluated the strength of samples that underwent no aging, hygrothermal and thermal aging, tested through three-point bending tests. Various load levels were tested utilizing a recently designed fixture, including 70%, 60%, and 50% of the static load level. Results showed the highest joint strength in Aluminum/Aluminum SLJs and reduced strength following thermal and hygrothermal aging. The failure patterns and number of cycles leading to failure also varied with load percent and aging. Ultimately, the study aimed to evaluate and contrast the strength of samples that underwent different aging processes.KEYWORDS: Jointstatic and fatigue strengthhygrothermal and thermal conditionsbending load AcknowledgementThis research has been jointly supported by The China's Liaoning Province 'Xing Liao Talents Plan' Youth Top-notch Talent Funding Project under Grant No.XLYC2007146 and Science and Technology Research Plan of China Railway 19th Bureau Co.,Ltd under Grant No.2021-B03.Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingChina’s Liaoning Province “Xing Liao Talents Plan” Youth Top-notch Talent Funding Project (No.XLYC2007146).
