Damage accumulation in woven-fabric CFRP laminates under tensile loading: Part 1. Observations of damage accumulation

Damage development in composite laminates reinforced with two-, four- and six-layer carbon-fibre-reinforced polyimide eight-harness satin-weave fabric has been observed as a function of applied strain. Residual properties (Young’s modulus, Poisson’s ratio and residual strain), together with damage a...

Description
Summary:Damage development in composite laminates reinforced with two-, four- and six-layer carbon-fibre-reinforced polyimide eight-harness satin-weave fabric has been observed as a function of applied strain. Residual properties (Young’s modulus, Poisson’s ratio and residual strain), together with damage accumulation, have been recorded as a function of applied strain. Distinct differences which emerge in the behavior of the residual properties of the laminates with increasing applied strain are related to the different types of damage which accumulate in the laminates.
