Two types of composite joints, co-cured and secondary bonded joints are used in the industries. Co-curing of composite joints is an efficient and cost-effective method of joining composites. The objective of this research is to enhance the bond strength between the composite material and adhesive, specifically in this study the bond between carbon-epoxy prepregs and an epoxy adhesive. The research investigated how the use of atmospheric plasma treatments of the uncured composite prepreg influenced the fracture toughness of the co-cured composite joints. The use of atmospheric pressure plasma treatment in the surface activation of prepregs was examined using contact angle measurements and X-ray photoelectron microscopy (XPS). Failure mechanism of the co-cured composite joints was studied by double cantilever beam (DCB) tests. Composite interface morphology was examined by scanning electron microscopy (SEM/FIB).||Type of material:||Conference Publication||Publisher:||Adhesion Society||Copyright (published version):||2010 the authors||Keywords:||Carbon/epoxy composite fracture toughness; Atmospheric pressure plasma treatments||Language:||en||Status of Item:||Peer reviewed||Conference Details:||33rd Annual Meeting of the Adhesion Society.
