Shape effect on the performance of carbon fiber reinforced polymer wraps
In this paper, the effect of corner radius on the performance and efficiency of carbon FRP (CFRP) laminates was investigated using a test device and method, which is relatively simple, reusable and can simulate the interaction mechanism between the FRP laminate and the substrate material. The test device has a symmetric configuration and the FRP laminate is wrapped around the outside surface of the device and anchored by lap splicing. From this investigation, it was found that the structural member cross sectional shape plays an important role on the strength development of FRP wrapping. Due to the higher stress concentration, for noncircular sections with small corner radii, the strength development and the efficiency of confinement by FRP wrapping is minimum. Increasing the corner radius accordingly improves the efficiency. However, only about 70 % of the ultimate strength of carbon FRP laminate can be developed even for the circular cross sections of sections with a large enough radius. The developed test device and method are viable to investigate the efficiency of FRP wrapping systems applied to cross sections with various corner radii.
