Fragmentation analysis of single-fiber carbon composites

Abstract

The effects of fiber surface oxidization and sizing treatment on both fiber strength distribution and fragmentation behavior in single carbon fiber epoxy composites are investigated experimentally. Based on the above experimental data, the fiber/matrix interfacial properties are discussed. It is found that the effect of fiber surface treatment on the fiber strength distribution is small and that the interfacial shear stress increases when applying fiber surface oxidization and sizing treatment in the carbon fiber/epoxy system used in the present study.
