철도차량 부쉬용 방진 천연고무의 카본블랙 강화제에 의한 피로수명과 파단 모폴로지 변화 연구

초록

The effects of carbon black on the fatigue life and the fracture morphology and the carbon black dispersion of the carbon-black filled natural rubbers, for the vibration-proof, were investigated. Different kinds of carbon blacks resulted in different fatigue life and fracture morphologies, which are classified by micro-scale and macro-scale fracture morphologies. These results be related to the size distribution of carbon black particles, the development of the carbon black agglomerate and the combine forces between the carbon black and the natural rubber.
