A plastics composite of fibres in a thermoformable matrix is formed by contacting the composite with a sheet of metal and deforming the metal plastically. The thermoformable matrix may be thermoplastic or thermosetting and the metal may be superplastic. The matrix may be deformed between the sheet and another sheet or between the sheet and a mould. Thin bodies of complex shape may be formed.
