Abstract: A multipurpose, automatic, self-contained device for manufacturing or repairing a workpiece made from a composite material includes a frame having an upper frame member and a lower frame member. A mechanical apparatus for providing a compressive force is mounted to the lower frame member and a lower platen is mounted to a movable member of the apparatus. An upper platen, positioned opposite to the lower platen, is mounted to the upper frame member. At least one heater is associated with at least one of the platens to apply heat to the workpiece and at least one temperature sensor is provided for mounting to the workpiece. The lower platen is moved toward and away from the upper platen by the mechanical apparatus to apply a compressive force to the workpiece disposed between the platens as a function of the temperature sensed from the workpiece and/or according to a predetermined schedule or plan.
