Abstract

Electrical resistors (12) are incorporated in a forming tool (10) having an upper forming surface (11) on which to deposit a superimposed arrangement of reinforcing- fibre sheets (C).A vacuum bag (V) is placed on the reinforcing-fibre sheets. An openable cover (13) is arranged on the tool to define a hermetically sealed space (22) therewith. A vacuum pump (16) withdraws air from the forming surface (11) and an inlet line (18) admits pressurized air to the space (22) through the cover (13). Optional resin-supply ducts (20) open in the forming surface (11).
