Effects of tensile loading angle on the stress-strain behavior in CFRP laminates are investigated experimentally. A material system used is T300/2500 carbon/epoxy system. Both a cross-ply and a woven laminates are used. The nonlinear behavior in the stress-strain curve is focused. To divide the total strain into the elastic and inelastic ones, loading-unloading tests are performed. Plasticity models are made to characterize the nonlinearity in the stress-strain curves.
