초록

roll mil1을 사용하여 maleic anhydride(MAH)-g-polyethylene(PE) (g-PE)에 aramid 단섬유를 보강시킨 복합재료를 제조하였다. 섬유의 loading이 작은 범위에서는 복합재료의 탄성율과 강도가 matrix보다 작아지는 이른바 희석효과가 나타났으며, 강도보강은 l0wt% 이상에서 나타났다. 또한 희석효과는 g-PE의 탄성적 본질에 기인한 것으로 보이며, g-PE의 탄성은 grafting 과정에서 야기된 연쇄간 가교화 반응에 의한 것임을 유변물성측정에서 알 수 있었다. 아울러 섬유함량의 증가와 더불어 복합재료의 점도 및 완화시간이 길어 짐을 볼 수 있었다.

Maleic anhydride(MAH)-g-polyethylene(PE)(g-PE) was reinforced with short aramid fiber on a laboratory open roll. Dilution effect, i.e., strength of the composite lower than the matrix, was observed at low, and strengthening was obtained at ≥10wt % loading. This was interpreted in terms of elastic nature of the g-PE, which on the other hand, was introduced by crosslinking at the stage of grafting, as evidenced from the rheology measurement. Melt viscosity and relaxation time increased with the increase of fiber loading.
