Abstract

Rehabilitation of damaged infrastructure has become a priority in recent years as an alternative to the daunting costs of rebuilding structures. Traditional strengthening methods have drawbacks, many of which can be overcome through the use of carbon fiber reinforced polymer CFRP. Considerable research has been directed to investigate the effectiveness of bond length and strength between CFRP and steel. Research results indicated that significant increase in strength due to CFRP strengthening can be obtained. Nevertheless, in-depth understanding of debonding failures along the steel-epoxy interface is still a challenging issue. This paper presents three different experimental models with new surface preparation to increase bond strength and control debonding failure between CFRP fabrics and steel. The experimental results indicated that debonding failure can be controlled to some extent with proposed surface preparation technology.

拉伸荷载作用下CFRP与钢粘结特性试验研究

近年来，修复受损的基础设施已成为一项优先事项，作为重建结构的一种替代方案。传统的加固方法有缺点，其中许多可以通过使用碳纤维增强聚合物CFRP来克服。大量的研究已被用于研究碳纤维布与钢之间的粘结长度和强度的有效性。研究结果表明，CFRP加固可以显著提高强度。然而，深入了解沿钢-环氧界面的脱粘破坏仍然是一个具有挑战性的问题。本文提出了三种不同的表面处理实验模型，以提高碳纤维布与钢之间的结合强度和控制脱粘破坏。实验结果表明，所提出的表面处理工艺可在一定程度上控制脱粘失效。
