Abstract
This thesis addresses two critical issues of laminar carbon fibre composites: manufacturing technology against delamination and failure prediction of composite structures with shallow surface scratches. A unique SAFE (Short Aramid Fibre Epoxy) toughening method was developed to strengthen weak interfaces between carbon fibre plies. Experimental results demonstrated synchronous effects of strengthening, stiffening and toughening by the SAFE design. A path to potential SAFE carbon fibre prepreg manufacturing has been established for impact resistant composites. A new fracture mechanics model for safety designs was developed, which was used to predict maximum fracture loads of composite structures with shallow surface scratches.
