METHODS FOR PRODUCING A MATRIX FOR PRESSURE FORMING OF WORKPIECES

A forming die for pressure-forming workpieces comprises a die core and a core reinforcement in the form of a reinforcement member made of fibre-reinforced plastics material. The reinforcement member is radially pretensioned against the die core and comprises a plastics matrix and a reinforcing fibre...

Zusammenfassung:	A forming die for pressure-forming workpieces comprises a die core and a core reinforcement in the form of a reinforcement member made of fibre-reinforced plastics material. The reinforcement member is radially pretensioned against the die core and comprises a plastics matrix and a reinforcing fibre structure which is embedded in the plastics matrix and which extends in the peripheral direction of the die core. A method for producing the forming die includes applying the the fibre-reinforced plastics material to the die core so as to produce a radial pretensioning of the reinforcement member against the die core.
