Abstract
To investigate the thermal ageing mechanism of carbon fibre/epoxy composites under high temperature (around 110 deg C), the present study examined the inter-laminar shear properties and curing degree. Experimental results showed the inter-laminar shear strength of carbon fibre/Epoxy composites firstly increased following with the ageing time increase which caused by secondary cure, then reduced for long-term of thermal stresses. Fourier transform infrared spectroscopy analysis revealed that the hydroxy functional groups had a certain growth which confirmed that secondary cure occurred during thermal ageing. Electron paramagnanetic resonance results indicated that the increase of the intensity of free-radicals may cause by the chain breaking. Also scanning electron microscopy (SEM) images of fracture surface indicated that carbon fibre and matrix had well combination, which contributed to the better residual shear properties. 7 Refs.
