Abstract

The aim of this work is to investigate the bearing failure of mechanically fastened joints between thin-ply angle-ply laminates with central 0° plies. To achieve this, pseudo-ductile laminates with two different layups [±266/0]s2 and [±252/0]s4 were loaded in a double shear-lap bolted joint configuration in tension. The major focuses of the experiments were to investigate the bearing strength and compare the bearing behaviour between pseudo-ductile laminates with different layups. Constant clamping pressure, edge distance-to-diameter ratio and width-to-diameter ratio were selected across the tests. Although gradual failure was exhibited in both layups, the [±266/0]s2 laminate has shown a higher bearing strength and larger deformation at the hole edge compared to the [±252/0]s4 laminate. The damage mechanisms of both layups were also similar, in the sequence of compressive damage at the hole edge, splitting in angle plies, tensile fracture and tear-out failure.
