Fatigue delamination of a carbon fabric-reinforced epoxy composite with carbon nanotubes
Original language description
Carbon fibre-reinforced epoxy composites are used in aerospace applications as primary aircraft structures where material fatigue can be an issue. Carbon nanotubes (CNTs) appear to enhance the fatigue resistance according to literature. This work presents the results of precise crack growth rate measurement on double cantilever beam (DCB) specimens made from a carbon fibre fabric-reinforced epoxy composite. Two plates were evaluated where the resin was enhanced using 0.5 % CNTs and a flame retardant forone of the plates. Loading in mode I was displacement controlled with R = 0.1, f = 4 Hz and a constant maximum strain energy release rate (GI)max during the cycle. The value of (GI)max was defined to be 20 % up to 60 % of the mode I interlaminar fracture toughness. The crack length was determined from the modified compliance calibration (MCC) method by video-recording the specimen edges. The specimens enhanced by CNTs had a significantly decreased fatigue crack growth rate by approximat
