Performance Improvement of Aramid/Epoxy Composite by Surface Treatment of Aramid Fiber

초록

아라미드 섬유강화 에폭시 복합재료의 기계적 물성향상을 위해 아라미드 섬유표면의 화학적 개질을 시도하였다. 화학적 개질의 방법으로 아라미드 섬유를 브롬화 후 아민화시켜 섬유표면에 아민기를 도입하였다. 적외선분광분석기를 이용하여 아라미드 섬유표면에 도입된 아민기를 확인하였으며, 도입된 아민기에 의해 아라미드 섬유와 에폭시 사이의 계면결합력이 증가하여 층간전단강도 및 굴곡물성이 향상됨을 관찰하였다. 주사전자현미경을 이용하여 섬유표면 및 복합재료의 파단면을 관찰하였다. 아라미드 섬유의 아민화는 섬유표면의 모폴로지 변화를 유도하여 섬유와 에폭시 수지 사이의 물리적 결합을 증가시킬 뿐만 아니라 섬유표면의 아민기에 의해 화학적 결합이 유도되므로 계면결합력이 더욱 증가하였다.

The surface of Aramid fiber was chemically modified in order to improve the mechanical at properties of Aramid fiber reinforced epoxy composites. Amine functional group was introduced on the fiber surface by bromination followed by amination. Amine functional group was identified by FTIR DRIFT technique. The interlaminar shear strength and flexural properties of the composites increased due to the improved interfacial adhesion through the armine functional groups. Aramid fiber surface and fractured surface of the composites were investigated with scanning electron microscopy. It was assumed that amination reaction induced not only the physical adhesion through morphological change but also the chemical adhesion due to the amine functional group.

Keywords:aramid fiber;chemical treatment;amination;interfacial adhesion
