Jadee Technical Engineering College-Baghdad, Middle Technical University, Baghdad, Iraq AJMSE2015321 10.12691/ajmse-3-2-1 2015 08 19 2015 08 25 2015 08 28 The performance of the glass fibre reinforced polymer (GFRP) composite bolted joint has been investigated using experimental and finite element methods. The glass fibre reinforcement was plain weave fabric of 800g/m2 weight. The investigation has been carried out on a double-lap composite bolted joint with many geometric parameters. Progressive failure analysis has been conducted using Hashin failure criteria to determine the failure load, failure mode and bearing strength. Failure map has been also defined with respect to the geometric parameters.
