A structural adhesive is most often used for engineering applications where joints will typically have lap shear strengths of greater than 1MPa and, more normally, greater than 10MPa. Thus, it may undergo shock, vibration, chemical exposure, temperature excursions or many other types of potentially weakening or destructive agents, and still be bonded. In this study, adhesive composition and curing temperature were optimized, and physical properties of thermally-cured adhesives such as swelling ratio in various solvent, cross-linking density and average molecular weight between cross-linking points were investigated. In addition, silanized nanocarbons as a reinforcement of the adhesive were prepared by the reaction between functional groups in nanocarbons and hydroxyl groups in silane coupling agents. |
