Large shear deformation of plain woven composite sheets and corresponding failure mechanism are investigated by bias extension test. Digital image correlation analysis was conducted on a series of photos taken during the test. Four typical phases were identified, and a theoretical model of the large deformation is proposed from energy point of view. Numerical simulations have also been carried out, but it will be reported in a subsequent paper.
