탄소섬유/에폭시 복합재료 접착조인트의 플라즈마 표면처리에 관한 연구

다국어 초록 (Multilingual Abstract)

When an adhesive joint is exposed to high environmental temperature, the load transmission capability of<br/>
the adhesive joint decreases because the stiffness and strength of structural adhesive decrease. The load<br/>
transmission capability of adhesive joint at high environmental temperature can be improved by increasing the<br/>
surface free energy of adherends with surface pretreatments. In this paper, a capacitively coupled radio<br/>
frequency plasma system was designed for the surface treatment of carbon/epoxy composites. The suitable<br/>
plasma surface treatment conditions were experimentally investigated with respect to gas flow rate, vacuum<br/>
pressure, power intensity, and surface treatment time through measurement of surface free energy by<br/>
investigating strength of single lap composite adhesive joint. Also the failure mode of the composite adhesive<br/>
joint was studied with respect to surface treatment and environmental temperature.
