Materials Research Institute Develops Induction Bonding Technology Based on Nanocomposite Aerogel
Published2026.10.01 10:12
The research was led by Principal Research Scientist Oh Young-seok's team at the Fusion and Composite Materials Research Division.
By utilizing nanocomposite aerogel as a bonding medium to simultaneously generate electrical heating and magnetic heating, the institute explained that the initial heating rate was increased by up to 94.6% and bonding strength was improved by 30.8%.
The conventional method relied only on electrical heating from the carbon composite itself, resulting in non-uniform temperature distribution at the bonding interface.
According to the institute, this technology additionally generates magnetic heating through magnetic iron oxide nanoparticles, uniformly heating the entire carbon composite.
Polyamide 6 serves as a binder for the aerogel structure and increases the integrity of the bonded joint.
Carbon composites are increasingly used in this field due to their light weight and high strength; however, the speed and uniformity of joining processes have been identified as obstacles to expanding mass production.
The institute conveyed that the research results are significant in that they present a direction to technically complement these limitations.
