Abstract
The fatigue crack propagation behaviour of a conventional polymethylmethacrylate (PMMA) bone "cement" was examined and compared with those of a low-viscosity PMMA cement and a carbon-fibre reinforced PMMA cement. The low-viscosity PMMA cement, developed for use in cement pressurization systems, did not differ significantly from conventional PMMA cement in its crack propagation behaviour. The carbon-fibre reinforced PMMA cement exhibited crack propagation rates which were approximately an order of magnitude less than those of conventional PMMA at the same range of stress intensity factor. Fractography of the test specimens revealed separation around prepolymerized PMMA beads and void formation around barium sulphate particles. Examination of carbon reinforced PMMA specimens showed poor mechanical bonding between the carbon fibres and the PMMA with considerable fibre pull-out and evidence of fibre breakage.
