During the extruding process of short fiber-rubber composite material, screw speed is an important factor which influences the orientation of short fibers, as well as the physical and mechanical properties of short fiber-rubber composite material. The effects of different screw speeds on physical and mechanical properties of short fiber-rubber composite material have been studied by experimental study. In the experiments, the screw speeds were 10rpm, 15rpm, 20rpm, 25rpm and 30rpm respectively. The experimental results indicated that when the screw speed was 15rpm, the physical and mechanical properties of short fiber-rubber composite material are better.

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 composite material 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-rubber composite material.

The structure of rotors is an important factor, which impacts the quality of the mixed rubber. For the short fiber-rubber composite material, the structure of the rotors is most important. Through the experiments study, the mixing performances of four-wing synchronous rotor, six-wing synchronous rotor and new type of six-wing synchronous varying clearance rotor have been studied. The experimental results indicated that the mixing performance of the new type rotor is much better than the four-wing and six-wing synchronous rotor for the mixing of short fiber-rubber composite materials.

Extrusion and molding is one of the most important manufacturing processes of short fiber-rubber composite material. In order to be used to tire tread, the short fibers in rubber are wanted to be radial orientated. But the orientation of short fibers depends on the die structure, and the performances of short fiber-rubber composite material depend on the radial orientation degree of short fibers. So, the die structure has been studied by experiments in order to get a proper die structure for manufacturing of short fiber-rubber composite material. The experimental results indicate that the proper die structure parameters are: the molding length is 15mm, the molding height is 9mm, the channel length is 75mm, the channel height is 12mm and the channel angle is 135º.

Vulcanization Process

Vulcanization process is the last step of manufacturing rubber products. For tire tread which is made of short fiber rubber composite material, vulcanization is complex due to during vulcanization process the flow of mixed rubber maybe change short fibers orientation. As a result, during vulcanization process, several pieces of iron wire have been put in the mold to play the role of tire patterns for the first step research. The experimental results indicate that the flow of mixed rubber would not change short fibers orientation greatly, and physical and mechanical properties of short fiber-rubber composite material keep as good as that vulcanized without iron wire.

The mixing mechanism of short fiber/rubber composite was analyzed. The clearance between the rotor edge peak and mixing chamber influenced mixing, dispersion and length of the short fibers in compound. The new rotor was designed with variable clearance. The large clearance gap improve the mixing, and the small clearance gap helped to improve the dispersion of short fiber. The mixing quality and performance of short fiber/rubber composite were improved by using the new rotor, and the production efficiency increased.

The Ideal

The ideal effects of mixing the short fiber-rubber composite can not be reached under current conditions. This paper built the physical model for the short fiber mixes and disperses in rubber through studying the mixing mechanism of the short fiber-rubber composite. The new 6-wing synchronous rotor was designed according to the requirement of material mixing mechanism. The mixing requirement of the ordinary material and the reasonable length-diameter ratio of the short fiber could be met through changing the clearance gap between the rotor edge peak and mixer room. Finally, verify the theory through experimental study.

Rubber Composite

Mixing is the first step for rubber processing. For the short fiber-rubber composite materials, whether the short fibers, carbon black and other additives in the rubber are dispersed well or not has a direct bearing upon the subsequent processing of materials and final performance. Because of the softness of the short fibers, they are easy to group or break during the process of mixing. The research in this paper is conducted by experiment on the methods which are applicable for mixing or mixing rotor of short fiber-rubber composite materials so as to guarantee the materials have good dispersion and the short fibers have rational L/D ratio.
