Abstract: A method of making a mould for moulding polymeric composites comprises embedding at least one layer 30 of a fibre reinforced polymer and a plurality of heating elements 24 within a spreadable ceramic material 28. The curing temperature of the ceramic material is less than the melting point of the polymer. The ceramic material is cured at a temperature less than the melting point of the polymer to yield a solid ceramic body, and the ceramic body is then heated at a temperature above the melting point of the polymer so that the latter is fused with the fibres to strengthen the mould. The mould is suitable for use for the manufacture of polymeric composites. A process for moulding polymeric composites using the mould is also described.
