【摘要】：为了研究高温下碳纤维增强复合材料(CFRP)筋材的力学性能,对不同直径的CFRP筋材进行了高温下的三点弯曲性能和压缩性能测试,研究了CFRP筋的破坏形态和机理,分析了直径和温度对CFRP筋材弯曲强度和压缩强度的影响。结果表明,直径对试样弯曲强度和压缩强度的影响不太明显,温度对试样弯曲强度和压缩强度的影响较大;CFRP筋材的强度保留率随着温度的升高而降低。
[Abstract]:In order to study the mechanical properties of carbon fiber reinforced composite (CFRP) tendons at high temperature, the three point bending and compression properties of CFRP tendons with different diameters were tested at high temperature, and the failure patterns and mechanism of CFRP tendons were studied. The influence of diameter and temperature on bending strength and compression strength of CFRP bars was analyzed. The results show that the influence of diameter on the bending strength and compression strength of the specimen is not obvious, and that the temperature has a great effect on the bending strength and compression strength, and the strength retention rate of CFRP bars decreases with the increase of temperature.
