Abstract: Rotor speed is an important factor which impacts the mixing process and quality of mixed
rubber greatly. The effects of different rotor speeds on manufacturing process of short fiber rubber
composites tire tread have been studied by experimental study. In the experiments, the rotor speeds
were 50rpm, 60rpm, 70rpm and 80rpm respectively. The experimental results indicated that the mixed
rubber after vulcanized had better physical and mechanical properties as the rotor speed was 70rpm. So
the rotor speed that is 70rpm has been chosen for manufacturing short fiber posites tire tread.
Key words: composite material; tire tread; short fiber; mixing; experimental study
0 Introduction
Short fiber and posite material (SFRC) which is manufactured by
mixing rubber, polyester short fiber and pounding ingredients has been
developed and used widely in almost all kinds of rubber products due to its good
performances[1~3]. The rubber products that are made from SFRC have good quality
such as high modulus, high tearing strengt
