EVALUATION OF GEOMETRICAL SIZE AND TEMPERATURE EFFECTON THE MECHANICAL BEHAVIOR OF CFRP BARS

Abstract

Abstract: In order to reveal the mechanical behavior of the carbon fiber reinforced polymer (CFRP) at elevated temperatures, different diameter CFRP bars were investigated by the three-point bending test and compression test at a range of temperatures from 25℃ to 150℃. The failure mode and mechanism of CFRP bars were investigated and analyzed to elucidate the effect of diameter and temperature on bending strength and compressive strength. The results show that the influence of the diameter on the bending strength and compressive strength is not obvious. However, the bending strength and compressive strength of the specimen are greatly influenced by temperature. And the strength retention rate of the CFRP is decreased with the increase of temperature.

Key words: CFRP bars, temperature, flexural properties, compressive property, failure mechanism
