Abstract: Both ceramic and intermetallic materials as a rule have a very small elongation at break of distinctly less than 0.3% and therefore a break behaviour with low damage tolerance. In order to increase the damage tolerance, it is important to increase the elongation at break to at least 0.3% or more. This can be achieved by introducing, for example, fibres consisting of carbon or ceramic or metal fibres into the matrix. It is important in this respect for the distribution of the fibres in the matrix to be homogeneous and/or defined. It is of advantage and therefore as a rule desirable for the fibres for reinforcing a material or component to be oriented in a defined direction which is adapted to the main stress. Therefore, according to the invention, a fibre-ceramic composite is proposed which consists of a ceramic matrix with a pore proportion of 0% to 75% and a fibre proportion of 5% by volume to 30% by volume, wherein the distribution of the fibres in the matrix is homogeneous and/or defined, and their quantity and orientation are optimised in relation to the material load.

Abstract: The friction heat generated between both sliding pairs and friction pairs has to be swiftly dissipated in older to maintain a lubricant film or ensure constant coefficients of friction. The invention consequently relates to metal-ceramic composites for friction/sliding uses, which are characterized by basic compositions containing 30 to 75 percent by volume of one or several metallic phases, preferably aluminum and the alloys thereof, and 25 to 70 percent by volume of one or several non-metallic inorganic component/s as ceramic materials, preferably silicon carbide, aluminum oxide, titanium oxide, and silicates.

Abstract: The production of moulded bodies from hard-metal powders by pressing and simultaneous or subsequent heat treatment is known. The mixture of hard material powders and aluminium powders for producing dry-pressed moulded bodies is an example thereof. As a result of the risk of demixing and the loss of homogeneity, the upper limit, for example according to prior art, for the proportion of hard material particles added to the aluminium powder is approximately 20 vol. %. The aim of the invention is to increase the proportion of hard material particles it the mixture. To this end, the inventive method for producing metal ceramic composite materials is characterised by dry-pressing powders with base compositions of between 25 and 79 vol. % of at least one metallic phase, preferably aluminium and the alloys thereof, and between 75 and 21 vol. % of at least one non-metallic inorganic constitnent, as ceramic materials, preferably silicon carbides, aluminium oxides, titanium oxides, carbon and silicates.

Abstract: A composite of a metal matrix with one or more incorporated secondary phases is referred to as a metal matrix composite (MMC). Secondary phase refers to all the particles or fibers which have a different composition than the metal matrix, and which are incorporated therein. As incorporation phases, elements and compounds are possible which, as a result of their material characteristics, are suited for improving individual properties of the metal matrix.Besides an improvement in individual properties of the pure metal matrix as a result of the incorporated secondary phase, certain properties of the metal are also degraded, in particular by particles having a size of 1 to 50 μm. For example, the elongation at break decreases, the strength may decrease, or the tribology may become less favorable. The object of the invention is to improve the properties of the composites by an appropriate selection of the size and type of fibers and/or particles in the secondary phase, and/or the formation of a special pore structure in the preform.
