Beschreibung
Zusammenfassung:	The invention relates to a composite material, particularly for the fabrication of static components for machines, and a static component for machines made with the said material. The composite material consists of a mixture of at least one epoxy resin with inert fillers of quartz and/or slate granules, particularly microspheres of quartz and/or slate. Waste dust from the working of Widia may be added in the form of a mixture with the epoxy resin or in the form of deposits in suitable chambers (2,7'). Further disclosed is a process for the fabrication of static components for machines (1) by moulding, particularly by what is known as the vacuum bag (5) method. Thereby, the filled mould is placed in a bag (5) which is then evacuated so that it adheres firmly to the mould. Afterwards the epoxy resin composition is cured. Also described is the production of objects with a non-uniform distribution of the fillers therein.
