Abstract
The fracture behaviour of hybrid-particulate composites has been examined. These novel materials contain both dispersed rubbery and rigid glass particles, and values of the stress-intensity factorK lc and fracture energyG lc have been determined using a double-torsion test. Considerable increases in toughness have been recorded and the mechanisms of toughening have been identified. The rigid glass particles increase the crack resistance mainly through a crack-pinning mechanism whilst the rubbery particles, which have a much greater effect, enhance the extent of localized plastic shear deformations around the crack tip. Quantitative failure theories and criteria are suggested for these mechanisms.
