Effect of Nanoparticle Modification on Composite Mode II Delamination
The effect of nanoparticle modification on the interlaminar shear fracture behavior of carbon fibre/ epoxy laminates were studied by the End Notched Flexure (ENF) tests. The mode II fracture toughness was improved in the presence of these nanoparticles although nano-rubber was more effective compared to nano -silica. Examination of the fracture surfaces of composite laminates by scanning electron microscopy showed no debonding of nano-silica particles but some evidence of nano-rubber cavitation. Anti-Symmetric Four- Point Bending (ASFPB) tests of the nanoparticles modified epoxies was conducted and the results indicated that nano-silica was more effective in toughening bulk epoxy, but this high toughness could not be effectively transferred to mode II delamination in the composite laminates. Finite element analysis was performed to confirm the predominant Mode II stress state of the ASFPB test.
