Description
Summary:The resistance response to temperature change of carbon fiber reinforced cement-based composites （CFRC） is reported, which shows some outstanding phenomena of positive temperature coefficient （PTC） of resistance and negative temperature coefftcient（NTC） of resistance during the temperature rising. The influences of carbon fiber, cement-based matrix and thermal cycles on the characteristics of temperatare-resistivity for the system were also discussed. Because of the special characteristics for temperature-resistivity, carbon fiber cement based composites can be useful in structure with the function of alarm for fire.
