The strength of metal materials is far less than the new composite material, such as carbon fiber. However, the price of the metal material and manufacturing cost are much lower than composite materials, which makes isotropic material much more practical for flywheel rotor. Through the stress analysis of isotropic material rotor, we can optimize the parameters of the rotor, thus for isotropic material provides the basis for the design of the rotor for flywheel battery.

The paper relates laboratory experiments in order to obtain a composite material used for brake shoe manufacture. Regarding the testing materials were processed 38 samples. The percentage and composition of materials are: 15-45% novolac, 1,5-10% hexametyltetramin, 0-8% sulfur, 0-15% carbon fiber, 0-20% graphite, 0-25% aluminum, 15-28% brass and 0-40% rubber. The evolution of tribological and temperature parameters were analyzed in the contact zone tribological testing disk - split pin method. The composite material has the role to replace the classic material (cast iron) used in brake shoes composition in order to reduce the noise caused by rolling stock.

In this study, thermal responses of advanced fiber/epoxy matrix composite materials are considered for spacecraft thermal design. These thermal responses are important, because the localized thermal behavior from applied heat loads can induce thermal stresses, which can lead to functional failure of the spacecraft system. Since most of polymer matrices exhibit relatively poor thermal conductivity, the composite materials have been widely considered only for structural application and little for thermal application. However, recently pitch-based high performance carbon fiber becomes available and this fiber shows high thermal conductivity. Because of this combination of low CTE and high thermal conductivity, continuous carbon fiber composites make them suitable for thermal management of spacecraft. The advanced composite material is composed of a continuous high modulus pitch based fiber (YS90A) and DGEBA epoxy resin(RS3232). It was demonstrated that advanced composite material satisfied thermal requirement for a lightweight thermal radiator for heat rejection of communication satellite.

With the development of social economy, composite materials enhance thepractical application of non-ferrous metal materials in production, meet the needs of current development, and better promote the development and progress of related industries. The application of composite reinforced non-ferrous materials is to add non-metallic reinforcing materials to non-ferrous materials, so that the properties of the original materials can be better changed to form a new composite material. This composite will have better performance than the original material and can meet deeper applications of non-ferrous materials. In this paper, the research on composite reinforced non-ferrous materials will focus on the analysis of the performance of non-ferrous materials. It is hoped that the research in this paper can provide some references and suggestions for the development of non-ferrous materials.
