The purpose of this work is to present a clear fundamental thought for designing and investigating straight bevel gear made of composite material. Composite materials have the advantage of being light, producing low noises, and extra loading capacities. Due to these properties, it is highly preferable over conventional materials. A comparison between different types of material used in a gear structure will be shown. The outcome shows that a new form of cheap material may be useful for designing a new type of lighter and stiffer gear, designed for robotic arm applications or any power transmission application.

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.

A new type of metal composite material can be manufactured by controlling heating temperature and designing the layout of cooling pipes in hot forming process of ultra high strength steel. The yield strength of this type of metal material varies from 380 MPa to 1000 MPa continuously, and its strength limitation varies from 480 MPa to 1600 MPa continuously. In this new hot forming technology, boron steel named as 22MnB5 is stamped by one-step process of hot forming to obtain the metal composite material and manufacture the part consisting of the metal composite at the same time. The hot forming technology of U-shaped part consisting of the metal composite material is provided. Then the microstructure of the U-shaped metal composite material is analyzed and the tensile test is also implemented. The experimental results show the material properties have the characteristics of continuous distribution along the main direction of energy absorption during crash process, which indicates the feasibility of hot forming technology of the metal composite material. The top-hat thin-wall structure consisting of U-shaped metal composite material is employed to analyze the crashworthiness of the new type of metal composite material. By distributing the single phase material of U-shaped composite part properly, the energy absorption ability is increased by 58.7% and the crash force is decreased by 23.4%, which indicate the new type of metal composite material has the comprehensive performance of every single phase material. So the metal composite is a good alternative material in application of crash resistance.

In order to further enhancing the ratio of load of the current intelligent industrial robot to its weight, and making the structure and movement of the intelligent robot develop rapidly toward the modularization, flexibility and reconfigurable mode, a kind of new-type intelligent robot hand material with high strength, light mass and large damping is proposed in the paper. The new composition material and its performance are also introduced and discussed in detail. Based on it, the specific preparation method and technology of the new-type composite material are given. The experimental results show that the weight of the intelligent robot hand material proposed in the paper can reduce by about 30% under the premise of ensuring the good strength of the intelligent robot hand.

A new type of gradient boron alloyed composite material, containing boron alloyed core layers and stainless steel coatings around the core, were designed and prepared by composite casting and hot rolling. The evolution of microstructures, phases and precipitations, as well as their influence on hot rolling process and performance are investigated. A mixture of austenitic matrix and uniformly distributed borides are obtained in the hot rolled stainless steel with 2-2.5 % boron, while massive borides are in the length of 80-120 μm together with micro gaps at the interface between the borides, and the matrix is remained after hot rolling for the core layers with higher boron contents. Hot deformation would be hindered since more precipitations of these orthorhombic or tetragonal phases occur with an increase of the boron concentration in the core layers.

A new type of tubular machine in modular construction that can work either like motor or generator is presented in the paper. It belongs to the transverse flux machines class and operates based on the variable reluctance principle. Two topologies of the machine, with and without permanent magnets (PM), are approached here. A prototype of the tubular machine with electromagnetic excitation, having a stator core built from laminated sheets and the mover core made of soft magnetic composite material, was built and is shown in the paper. The use of the new soft magnetic composite material, Somaloy 700 HR, having 3D magnetic isotropy, brings important advantages in building the structure. The innovative construction, implying the alternation of the magnetic pieces called modules with no-magnetic spacers, has very good performances. A prototype of this machine was built and a test bench equipped with control and monitoring devices in order to perform experimental tests. Some possible applications showing the potential of the proposed machine are also presented.

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.
