Influence of Interface Modification in Fiber Reinforced Cement Composites on Their Properties

Abstract

This research aims at a further exploration of surface treatments of carbon fibers to improve the performance of CFRC. Two approaches to treat carbon fibers were used in this study. SEM, IR, XRD were used to analyse the CFRC prepared with treated carbon fibers. Because of strong adhesion, CFRC prepared using CF with treatment has a better performance than that without treatment. Flexural strength is 30% higher, tensile strength is 48% higher, impact strength 63% higher, and deflection is increased.
