Abstract Scope |
In the era of sustainability driven by undeniable societal needs, regulations are now rightfully pressing for a shift of focus on the use of materials, manufacturing and extended life cycle of engineering systems. Demountable bonding is an intriguing concept for sustainable engineering practices. Despite its highly anticipated positive impact also in significantly load-bearing engineering applications (e.g. in assembly of airframes and car chassis), bonding practices are yet to be converted from traditional irreversible structural adhesives. Such a paradigm shift, however is gearing up thanks to advances in reversible/re-processible high performance structural resins/adhesives and associated assembly/disassembly strategies. This paper aims to facilitate the use of such an emerging material choice, vitrimer resin, and Joule Heating as an enabling joining technology for on-demand assembly and disassembly. Success of this strategy will help to minimize, if not to eliminate, need for heavier mechanical joints for their assembly/disassembly advantages. It also has potential to enable in-situ diagnosis and self-healing modular design strategies. Carbon fiber/epoxy adherents will be bonded using vitrimer/nonwoven carbon fiber mat composite bonding agents/heating elements at the bondline. Single-lap joint configurations will be prepared using both hot-press and Joule Heating methods to compare joint strengths. |
