摘要
碳纤维增强水泥(CFRC)材料具有压敏性。考虑到受力情况不同,试样的变形不同,CFRC的压敏性也会有所不同。本文研究了碳纤维增强水泥试块在四周受约束情况下的压敏效应,并与单向受压情况下的压敏性进行比较。实验结果表明:CFRC材料在两种受压情况下电参数随压力的变化趋势相同;但在准三向受压情况下的压敏灵敏性有所降低,线性却更好。
Carbon fiber reinforced cement (CFRC) has compression sensibility. Considering the deformation of the specimen is different on the different load condition, the compression sensibility is different either. The compression sensibility of CFRC is studied when the specimen is restrained around the periphery and compared to the result measured under uniaxial compression. The result shows that the change trend of electric parameter with pressure on the two load condition is same and the sensitivity reduces when the specimen is restrained around the periphery, but the linearity is better.
