Abstract

This report provides an evaluation of the single-fibre fragmentation test for assessing the interface in polymer matrix composites (PMCs). All aspects of the technique are covered, from specimen preparation through testing procedures and test measurements to data handling/analysis. Step-by-step procedures are provided to enable test-pieces to be manufactured from constituent materials, with particular emphasis on the precautions required to achieve consistency and repeatability. Similarly, detailed information on the apparatus, measurement requirements and test procedure are covered.
An extensive experimental screening study was carried out and recommendations are made for the optimum specimen parameters/geometry and test protocol. The optimised fragmentation method was subsequently shown to be applicable to the determination of interfacial shear strengths in both glass and carbon fibre systems with different surface treatments and subjected to aggressive environments. The role of photoelastic microscopy to supplement the test method and provide complementary qualitative assessments of the interfacial adhesion and failure process was evaluated.
