Abstract

In this paper, stress distribution analysis and tensile strength assessment of CFRP bonded joint were studied. First a mixture of Epoxy adhesives and MWCNT was fabricated. Since failure is initiated at the ends of overlap, the stress distribution at the ends of the overlap and bonded joint was numerically analyzed. After the stress distributions were analyzed based on the result obtained the experimental steps were followed to assess the tensile strength of bonded joint. The stress distribution analysis and the tensile strength assessment results showed an agreement that the geometrical factors directly affect the reliability of the bond.

CFRP胶粘接接头的抗拉强度评价
本文对CFRP粘结接头的应力分布分析和抗拉强度评定进行了研究。首先制备了环氧胶粘剂和MWCNT的混合物。由于破坏发生在重叠端部,因此对重叠端部和结合部的应力分布进行了数值分析。在此基础上对应力分布进行了分析,并按照实验步骤对接头的抗拉强度进行了评定。应力分布分析和抗拉强度评估结果一致表明,几何因素直接影响粘结的可靠性。
