Title: Method for the extrusion of fibre composite materials
Inventor: MUELLER KLAUS DIPL ING
IPC: C22C47/00
Filed: 1981-03-12
Abstract: An extrusion method for the production of a fibre composite material with a plurality of fibres in a metallic matrix material is improved by indirect extrusion, from a bundle of sheathed wires, of a composite strand, the diameter of which corresponds to the diameter of one sheathed wire. The composite strands are then bundled in the same way as the sheathed wires and a new composite strand with a correspondingly increased number of fibres is extruded. Bundling and extrusion is continued in a number of stages until a matrix material with a predetermined number of embedded fibres has been produced. By this method it is possible, inter alia, to produce fibre composite materials in which a multiplicity of very thin graphite fibres are embedded in a silver matrix.
Patent DE-3111148-A1 (DE)
Inventor: KOPP REINER PROF DR ING
IPC: B21D31/06
Filed: 1981-03-21
Abstract: For the transformation of metal sheets and plates in a united direction, the invention provides an injection of the upper surface of the material by an oblong surface of the tool with a ratio of the length to the width of more than 3, particularly more than 6 avoiding at the maximum thickness modifications. The surface of the tool has the shape of a print. An inadmissible variation of the thickness also limits a large framing surface of the tool surface from 0.05 up to 0.5mm opposite to the stroke direction. The work piece bends due to the load, perpendicularly to the longitudinal direction of the tool surface. For a preset incurvation, the elastic tensions of the metal sheets, which are resiliently fixed, cancel each other by the load, so that, in connection with such treatement, the working piece may remain in the accurate and definitive geometric incurvation imparted by the tension means.
