Abstract
Short(4mm) aramid fiber reinforced rubber(SMR, SBR, NBR, BR, BR/SMR) composites have been prepared on a conventional open mill. The effects of fiber concentration, rubber type and fiber surface treatment on the mechanical properties of the vulcanizates were examined. Optimum fiber concentration for reinforcement was approximately 10 wt % for BR/SMR. The most pronounced reinforcing effect at 20 wt % fiber loading was observed for SBR. Surface treated aramid fiber reinforced NBR showed more than twice of the strength of the surface untreated aramid fiber reinforced NBR.

Aramid(4mm) 강화고무(SMR, SBR, NBR, BR, BR/SMR) 복합재로를 open mill에서 혼합 제조하였으며. 제조된 aramid단섬유보강가황고무의 기계적 특성을 섬유함량, 고무종류 및 섬유 표면 처리 효과의 관점에서 검토하였다. BR/SMR계에서는 섬유함량이 10∼20 wt%에서 강화효과가 나타났으며, 섬유함량이 20 wt%인 경우 강화효과는 SBR계가 최대였다. 또한, cresol-acetone-phenol계 수용액으로 aramid를 표면처리하여 NBR을 보강시킨 경우엔 미처리 섬유보강에 비해 강도가 2배 이상 증가 함을 알 수 있었다.
