Abstract Details

2005, MS, University of Cincinnati, Engineering : Materials Science.
Earlier DCB and lap shear failure results indicated that grit blasting and plasma etching of graphite/epoxy composites produced strong durable bonds. Grit blasting and oxygen plasma etching of graphite/epoxy composites were analyzed for their effects on surface energy, roughness, and changes in surface chemistry. Two systems of epoxy resin material were analyzed. Surface energy results for grit blasted composite panels showed a significant increase in surface energy. However, upon roughness corrections the surface energy was calculated to be lower. The resulting change in surface energy after roughness corrections is due to a change in surface chemistry. XPS results indicated that grit blasting and oxygen plasma etching removed surface contamination from a fluorinated mold release agent as well as introduce new functional groups onto the composite surface. Interaction of these functional groups with a brominated epoxy suggests covalent bonding is an important factor in the adhesion of graphite/epoxy composites.
