单根碳纤维(CFRP)预应力筋粘结式锚具的试验研究

A Research Into Bond-type Anchorage of CFRP Tendon

本文介绍了用环氧铁砂和普通混凝土作粘结介质的粘结式锚具对碳纤维(CFRP)筋的锚固性能.通过大量试验,研究了粘结式锚具锚固CFRP筋的性能,并分析了粘结式锚具的粘结机理,为CFRP筋在结构工程中的推广应用奠定了基础.

During the past half century, CFRP tendons have been used widely in different structures. But how to anchor the CFRP tendons and maintain the post-tensioning force is the most obstacle for CFRP tendons to be used widely in different structures. In this paper, the performance and anchoring capacities of a bond-type anchorage system with two different adhesive have been tested and analyzed. Epoxy iron sand and concrete have been used as adhesive.
