Developement of New Glass Fiber Reinforced Composite Insulating Material by Reactive Plasma Surface Treatment(II)

반응성 플라즈마 표면처리기법을 도입한 새로운 유리섬유 강화 복합재료의 개발 및 물성연구(II)

One of the principal problems encountered in the use of glass fiber reinforced Plastic composites(GFRP) is to establish an active fiber surface to achieve maximum adhesion between resin and fiber surface. In order to develope new process to overcome the disadvantage of chemical agent, we have studied the effect of reactive plasma glass surface treatment on the electrical and mechanical properties of glass fiber reinforced epoxy composites. It is found that the electrical and mechanical characteristics of the composites treated with plasma is improved especially in the dielectric strength by 20% and tensile strength by 15%, whereas the tan $\delta$ is decreased significantly.
