چکیده انگلیسی
The influence of water ageing on the evolution of damage during tensile loading in woven hemp/epoxy composites is studied. First, the water uptakes of several types of samples are compared. Micro-CT observations show that, from the beginning of desorption but not during the water ageing, damage appears in the composites. At macroscopic scale, tensile tests reveal a significant modification of mechanical properties of the composite after water ageing. Then, an original test, combining tensile loading and X-ray microtomography, is performed on a ±45 hemp/epoxy composite material. The volume of damage inside two specimens (with and without water ageing) at several steps during a tensile test can be quantified. Results highlight significant differences in the evolution of the volume of damage between the two samples. This work shows how the mechanisms of deformation and damage of plant fibre composites are governed by their moisture exposure history.
