Title
(DE) VERFAHREN ZUR HERSTELLUNG EINES VERBUNDKÖRPERS DURCH KOALESZENZ UND DER HERGESTELLTE VERBUNDKÖRPER
(EN) A METHOD OF PRODUCING A COMPOSITE BODY BY COALESCENCE AND THE COMPOSITE BODY PRODUCED
(FR) PROCEDE DE PRODUCTION D'UN CORPS COMPOSITE PAR COALESCENCE ET CORPS COMPOSITE AINSI PRODUIT
Abstract
(EN) A method of producing a composite body by coalescence, wherein the method comprises the steps of a) filling a pre-compacting mould with composite material in the form of powder, pellets, grains and the like, b) pre-compacting the material at least once and c) compressing the material in a compression mould by at least one stroke, where a striking unit emits enough kinetic energy to form the body when striking the material inserted in the compression mould, causing coalescence of the material. A method of producing a composite body by coalescence, wherein the method comprises compressing material in the form of a solid composite body in a compression mould by at least one stroke, where a striking unit emits enough energy to cause coalescence of the material in the body. Products obtained by the inventive methods.
(FR) L'invention concerne un procédé de production d'un corps composite par coalescence. Ce procédé consiste : a) à remplir un moule de pré-compactage d'un matériau composite sous forme de poudre, de pastilles, de granules et équivalent ; b) à pré-compacter le matériau au moins une fois et c) à comprimer le matériau dans un moule de compression avec au moins un coup, une unité de martelage générant suffisamment d'énergie cinétique pour former le corps lors du martelage du matériau inséré dans le moule de compression, provoquant la coalescence du matériau. L'invention concerne également un procédé de production d'un corps composite par coalescence. Ce procédé consiste à comprimer le matériau sous forme d'un corps composite plein dans un moule de compression avec au moins un coup, une unité de martelage générant suffisamment d'énergie pour provoquer la coalescence du matériau dans le corps. L'invention concerne enfin les produits obtenus selon les procédés de l'invention.
