The bearing strength of pin-loaded woven glass-fibre reinforced epoxy composites was investigated. To understand the effect of manufacturing methods on bearing strength of pin loaded composites, specimens manufactured using Vacuum Assisted Resin Transfer Moulding (VARTM) and hand lay-up methods were tested under tensile loading. In addition, the effects of geometrical parameters such as diameter of pin-hole (d), edge distance to pin hole diameter ratio (e/d) and, width to pin-hole diameter ratio (w/d) on the bearing strength of pin-loaded composites were studied. It was observed that specimens manufactured using VARTM method sustained more load compared to specimens manufactured using the hand lay-up method. Geometrical parameters were found to be very influential on the failure modes, bearing strength and magnitude of sustained loads.
