Filling factor and polyester short fiber addition impact the mixing process and performances of mixed rubber greatly. The effects of filling factor and polyester short fiber addition on mixing short fiber-rubber composite material have been studied by experimental study. And according to the experimental results, at the condition of filling factor was 0.6 and polyester short fiber addition was 3, the performances of mixed rubber were best.

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.

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.

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.

A new type of six-wing synchronous rotor has been designed and manufactured for mixing requirements of the short fiber-rubber composite material. During the manufacturing process of the composite material, different addition proportions of the short fibers have been used. The physical and mechanical performances of the short fiber-rubber composite material have been investigated. The new type rotor meets the mixing requirements of the short fiber-rubber composite material, with the best addition proportion of the short fibers.

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.

To study the damage effect of different projectile structures and jacket materials of PELE upon perforation of multi-layered plates, an experiment of three different kinds of projectiles impacting on multi-layered plates was conducted. The experimental results show that the layered PELE can change the characteristics of fragments broken by jacket which include quantity, mass and the area of distribution. The jacket of layered structure PELE can generate more number of fragments of uniform quality and centralized distribution than common PELE. So it results in the occurrence of cumulative damage effects on target plate. Using the W fiber /Zr-based amorphous matrix composites as the jacket material of PELE, the jacket can be broken into lots of single W fibers and W fiber bundle fragments, and the fragments distribute centrally. The impulse of the fragments loads on the plate intensively, which reduces the plate resistance and improves the opening size substantially.

Rotor speed is one of the most important technical characteristics of the internal mixer. The effects of rotor speed on mixing process have been studied. In the experiments, three types of synchronous rotors which were two-wing synchronous rotor, four-wing synchronous rotor and six-wing synchronous rotor were used. The experimental results indicated that there was a proper speed of different rotor structure for mixing process. And along with the increase of rotor speed, the maximum power, the unit consumption of energy and discharging temperature increase, while the physical and mechanical properties of mixed rubber got a better value.

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.
