Abstract

A study on the heating behavior and adhesion property of structural epoxy adhesive through induction heating have been conducted. An adhesive for induction heating was manufactured through mixing with nano and micro sized Fe3O4. From the results, it was observed that induction heating is less affected by adherend (GFRP) thickness than oven heating. The heating rate of Fe3O4 embedded epoxy adhesive using induction heating much higher than that of oven curing process and it is more appreciable when the contents of Fe3O4 increased. Furthermore, adhesion strength increased with increase of Fe3O4 particle contents.


구조용 일액형 에폭시 접착제에 나노 및 마이크로 크기의 Fe3O4 분말을 첨가하여 유도가열용 접착제를 제조하였고, 제조된 접착제를 이용하여 GFRP 피착재의 두께 및 Fe3O4 분말의 첨가량 변화에 따른 가열 성능을 평가하였다. 실험 결과, 접착제의 승온 거동이 유도 가열로 가열한 경우 오븐경화에 비해 GFRP 피착재의 두께에 영향을 작게 받는 것이 관찰되었으며 접착제 내의 Fe3O4 분말의 함량이 증가할수록 가열 속도와 전단 강도가 증가하는 경향을 나타냈다.
