Abstract

Abstract: The GFRP laminates with interlayer pre-embedded carbon nanotube films (CNTF) and carbon black films were treated with low-temperature cycling (-58 ℃~room temperature), respectively, followed by cantilever beam bending tests. By observing microscopic images, analyzing load-displacement curves and comparing bending ultimate loads, the effects of both films on the bending properties of GFRP laminates and the enhancement mechanism of GFRP laminates after low-temperature cycling were investigated. The test results show that CNTF has the most obvious strengthening effect on the laminate and is least affected by the low-temperature cycling energy. The carbon black film also has certain strengthening effect, but it is slightly weaker than CNTF.

Key words: GFRP, low-temperature cycle, carbon nanotube films, bending of cantilever beam
