Load-Bearing Capacity of Deviated CFRP Strips
Publication: Journal of Composites for Construction
Volume 18, Issue 4
Abstract
The paper presents experimental work to determine the load-bearing capacity, strain responses up to failure, and failure mode of pultruded carbon fiber–reinforced polymer (CFRP) strips with different deviation saddle geometries. Several tests with different deviation angles and deviation saddle radii were carried out. The results show that the tensile strength of the CFRP strip is reduced significantly by deviation, even if the deviation radius is comparatively large in relation to the thickness of the CFRP strips. Further tests were carried out to determine the influence of other important parameters on the load-bearing capacity of the strip such as surface properties of the saddle. With the help of a polyethylene layer (PE-HD) between the CFRP strip and the deviation saddle, friction could be reduced. This leads to an increase in the breaking strength of the CFRP strip. The effect of these parameters on the load-bearing capacity of the CFRP strip is presented in this article.
