S. Meretz et al., INVESTIGATION OF MORPHOLOGY-DEPENDENT FRACTURE-BEHAVIOR WITH THE SINGLE-FIBER PULL-OUT TEST, Composites science and technology, 48(1-4), 1993, pp. 285-290
In this study attempts are made to answer the question of how the morp
hology, and especially the transcrystallinity, influences the fibre/ma
trix adhesion in carbon-fibre/poly(phenylene sulphide) composites. The
refore, single-fibre pull-out measurements are performed with samples
containing high-modulus (HM) and high-strength (HS) fibres that had be
en subjected to different thermal treatments. Transcrystallinity leads
to a prevailing brittle fracture process in the interface and to high
er values of the apparent shear strength. Samples with HS fibres and h
igh crystallinity show an unexpected ductile fracture behaviour at a h
igh apparent shear strength level.
