Short nylon fiber reinforced(16wt%) styrene-butadiene rubber composites were prepared for V-Belt application. Cure characteristic. Morphological and mechanical properties of the composites were subsequently measured both in longitudinal and transverse dirrection, In addition, the retention of the mechanical properties after ageing for 96 hrs at 70℃, was also determined. The results obtained in these experiments were interpreted in terms of fiber surface treatment, and was found that resorcinol-formaldehyde-latex(RFL) was effective adhension system for nylon/SBR composites.
V-Belt제조에 이용할 목적으로 나일론 단섬유 강화(16wt%) styrene-butadiene고무(SBR)복합재료를 제조, 이들의 가황특성 및 복합재료의 형태학적, 기계적 특성을 측정하였다. 아울러 복합재료를 70C에서 96시간 노화시켜, 복합재료의 노화로 인한 물성변화을 검토하였다. 본 실험에서 얻어진 결과는 대체로 섬유표면처리효과로 설명 할 수 있었으며, nylon/SBR계의 경우 resorcinol-formaldehyde-latex(RFL)계 표면처리가 효과적임을 알 수 있었다.
