Research Institution
A versatile class of high-performance structural joints is proposed where massive interatomic bonds over the large surface areas of nanostructured surfaces constitutes the primary joining mechanism. The new nano-engineered joints embody nanomaterials which are self-assembled and anchored onto the joining surfaces. Compatible functionalization of nanomaterials on opposite surfaces creates favorable energetic conditions for their effective engagement and joining via massive primary (chemical) bond formation. Complementary self-assembly techniques will be used for rapid, low-cost, energy-efficient and environmentally friendly processing and anchorage of nanomaterials upon substrate surfaces. Various nanomaterials and anchorage conditions can be used for different substrates (ceramics, metals, polymers, composites) and service requirements. The length of nanomateials would be selected to compensate for the surface roughness. The proposed joints can be engineered to provide broad ranges of mechanical performance, accommodate various material incompatibilities (e.g., thermal expansion mismatch), and different functionalities (e.g., thermal/thermal conductivity, or reversibility). The proposed Phase I research will establish the theoretical potential of the proposed nano-engineered joints, and will develop and characterize a precursor joint system embodying the proposed joining principles in order to verify the technical merits of the technology and its commercial potential.
