Abstract: The invention relates to sheet-shaped products processable by means of flow molding comprising carbon fibers and a radical-curable resin as the matrix, the fibers being present in the form of mats consisting of fibers with lengths of more than 1 cm and the volume percentage of the fibers relative to the resin being less than 70%, and the fibers moving freely relative to one another in the mat during flow molding, resulting in a net end product with a homogeneous fiber distribution. The invention also relates to a process for the production of sheet-shaped products by impregnating carbon fiber mats with a radical-curable resin and thickening that resin to a desired thickness, and a process for the production of molded parts with a tensile modulus of >20 GPa and a tensile strength of >200 MPa.

Abstract: A curved multilayer ceramic moulded part, particularly curved in directions perpendicular to one another, is limited by two virtually parallel surfaces and an edge. Electrically conductive path(s) parallel to the surface are provided internally. The molded part may be produced by deforming a dish-shaped green moulding, formed from a composite of a self-supporting ceramic film having at least one electrically conductive path and at least one additional ceramic film, with or without electrically conductive path(s), to pressure from all sides. The deformed part is subjected to burning out and sintering. The moulded articles are virtually free of defects. Absolute deviation from the average shrinking of less than 2% may be obtained.

Abstract: The invention relates to a multilayer ceramic moulded part, limited by two virtually parallel surfaces and an edge, which internally contains electrically conductive paths parallel to the surface, characterised in that the moulded part is curved in at least one direction. In particular the invention relates to such a moulded part that is curved in two directions perpendicular to one another. The invention also relates to a process for the production of such a moulded part and to a laminate that is produced as an intermediate in the process.

Abstract: Disclosed is a fabric of thermoplastic fibers and continuous reinforcing fibers in which the shrinkage of the thermoplastic fibers is minimal, thus providing a product well-suited for processing as a thermoplastic composite prepreg. The thermoplastic fibers have a melting point lower than that of the reinforcing fibers, and are preheated at a temperature of from 50.degree. to 15.degree. C. below the melting point of the thermoplastic material before being processed to form the fabric.Fabrics of thermoplastic fibers and reinforcing fibers according to the present invention can be used in applications where sheets of fabrics must be drapeable, so that when subjected to cold forming they conform to the mold for the thermoforming process. Fabrics according to the present invention are especially useful in applications where the use of high-grade, fiber-reinforced plastics is advantageous.
