Carbon Black Reinforcement of Rubbers Part3. Recent Progress in the Researches of the Carbon Reinforcement Yoshihide Fukahori Polymer Engineering Design, Tokyo, Japan Nippon Gomu Kyokaishi, (2004), 77(3), 103-108 General Review in Japanese. Abstract In the last report,we summarized the researches published from 1950s to 1980s, Concerning phenomena,theories and models in the fields of carbon black reinforcement of rubbers.In this report,we would like to extract some more works from the reports published during these 20 years periods.Although these reports do not directly address the reinforcement of carbon black for rubbers,they are quite important,indeed essential,for understanding the mechanism and mechanics of the reinforcement. This presentation includes such results as,the stress analysis of rigid particle-filled system with large deformationFEM and the molecular slippage at the interface of carbon particle and matrix rubber at large extension and high temperature,and more over the volume expansion and the micro voids formation between adjacent carbon particles in the fine carbon black-filled rubbers under extension. Keywords: Carbon black, Reinforcement, Rubber, Stress analysis, Tri-Axial extension
