A Resistance Model of Carbon Fiber Composite Materials Based on Interfacial Effect

Abstract:

Based on the single fiber pull-out testing, the resistance of carbon fiber cement increases during the tensile test in elastic stage. Through the experiment, The fiber embedded length shorter, sample pullout strength is greater. But the resistance change rate is smaller, the lower the sensitivity of the sample. So, considering the fiber length and interface set interface effect of carbon fiber reinforced cement based composite resistance model. A simple model was proposed to explain the mechanism of compression sensitivity of carbon fiber reinforced cement-based composites based on interface effect. The results showed that the content of carbon fiber and interface strain can change the sensitivity of CFRC.
