    Although new generation alumina ceramics have exhibited a reduced incidence of fracture, concern still persists about the behavior of ceramic acetabular liners under impact conditions. The objective of this study was to explore whether fracture of a new generation alumina ceramic liner was likely to occur in vivo. Ceramic liners were impacted with forces of 23, 21, 15, and 12 kN (n = 3 at each force). At 23 kN, all 3 ceramic liners fractured on the first impact; at 12 kN none of the ceramic liners fractured after 20 impacts. The threshold force of 12 kN is large in comparison with estimated physiologic forces on the hip during falls or stumbling, suggesting that ceramic liner fracture is not a definite consequence of liner impact.

    The contemporary Formula 1 racing car makes extensive use of advanced composite materials in its construction. The design, manufacture, and ultimate performance under compression of composite suspension push-rods that typically could be used in a Grand Prix racing car are described in this present paper. An aerofoil cross section has been used based on different lay-ups of carbon/epoxy composite. One push-rod was manufactured using a uniform layup of unidirectional and woven cross-ply prepreg whilst a further three push-rods were manufactured with a tapered layup of unidirectional and woven cross-ply prepreg. Failure mechanisms including fibre microbuckling, fibre kinking and fibre fracture were observed whilst comparisons have been made between the experimentally observed failure strains and those that were predicted using simple buckling theory. The ultimate compressive strength of the structural component was significantly less than that of the carbon/epoxy composite.

    Advanced composite materials are extensively used in the construction of a contemporary Formula 1 racing car. This paper describes the manufacture and ultimate mechanical performance under compression of composite suspension push-rods that could typically be used in a Grand Prix racing car. An aerofoil-type cross-section was used with different lay-ups of unidirectional and woven cross-ply carbon/epoxy composite. Failure mechanisms including compression and buckling were observed and the ultimate strength of the component under compression was significantly less than that of the material
