Carbon-Carbon Composites . Carbon-carbon composites, i. e. carbon fibre reinforced artifical carbons, are a new type of composite material for high temperature applications. They exhibits strength values up to 100 kp/mm2 combined with densities lower than 2 g/cm3. Although at first developed for use in aerospace technology, in the last time they become more interesting for common applications because of their extraordinary properties. A process for the production of carbon carbon composites from commercially available endless carbon fibres and coal tar pitch as matrix precursor is presented. The properties of the composites are discussed in detail in relation to the production conditions. The high temperature strength under inert atmosphere is characterised up to 2000 °C. Literature is given for some newer applications of carbon-carbon composites. 相似文献

Current and future potential applications for three-dimensional (3D) fibre reinforced polymer composites made by the textile processes of weaving, braiding, stitching and knitting are reviewed. 3D textile composites have a vast range of properties that are superior to traditional 2D laminates, however to date these properties have not been exploited for many applications. The scientific, technical and economic issues impeding the more widespread use of 3D textile composites are identified. Structures that have been made to demonstrate the possible uses of 3D composites are described, and these include applications in aircraft, marine craft, automobiles, civil infrastructure and medical prosthesis. 相似文献

Aluminium foam composites – applications in railroad manufacturing After their rediscovery in the beginning of the 90ies foamed metals are now being produced on an industrial scale. In most applications the aluminium foam is used as composite material, i.e. in combination with other materials. The composites can be distinguished into flat or complex shaped sandwich structures on the one hand, and 3‐dimensional shaped foam parts on the other hand. The processes and feasible geometries are described. The material properties and the industrial applications are illustrated. Within a publicly funded project the utilisation of sandwich composites with an aluminium foam core layer was evaluated regarding applications for railroad vehicles. The central aim of the investigation was the production of a large segment of the vehicle’s front module. Results of this project are presented. 相似文献

Carbon‐nanotube (CNT) composites have attracted a lot of attention because of their potential applications in many fields. Here, recent advances in the synthesis of CNT composites using supercritical fluids (SCFs) are highlighted. SCFs exhibit unique features for the synthesis of composites because of their unusual properties, such as low viscosity, high diffusivity, near‐zero surface tension, and tunability. Preliminary studies show that SCFs show unusual advantages for the synthesis of CNT composites. The morphologies and structures of the resultant CNT composites can be tuned by changing the solvent properties. The SCF methods not only provide a green route for the synthesis of composites, but also result in nanostructures that have not yet been produced by conventional methods. Moreover, the potential applications of the resultant CNT composites are also discussed. 相似文献
