Interpretation of Experimental Results in the Single Filament Pull-Out Test.

Abstract

The experimental results of the single filament pull-out test which is used to directly examine fiber-matrix interface bond strength are interpreted using a fracture mechanics approach. The nonlinear relation between the pull-out (debond) load and the fiber-matrix interfacial area is explained by considering the separate contributions of the matrix and the fiber to the interface failure process. In addition, the large experimental scatter is demonstrated to be inherent in the small test specimen size and to be caused by fiber surface energy heterogeneity. Keywords: Composite materials.
