Abstract
An apparatus and method for consolidating a composite workpiece are provided. The apparatus includes an electromagnetic field generator for inducing a current and thereby heating a susceptor in thermal communication with the workpiece. The workpiece is supported by one or more support tools, each of which transmits the electromagnetic field so that the support tools are not substantially heated by the electromagnetic field. Thus, the time and energy required for heating the workpiece are reduced relative to conventional consolidation techniques.
Claims15
A method of consolidating a workpiece, the method comprising:
- providing first and second support tools in a face-to-face, opposing relationship;
- disposing at least one susceptor and workpiece between the support tools;
- generating an electromagnetic field, thereby inducing an electric current in the susceptors and heating the susceptors and the workpiece to a processing temperature, the support tools being substantially transparent to the electromagnetic field such that the electromagnetic field is substantially transmitted through the support tools;
- and
- advancing the workpiece, susceptors, and support tools through a nip and thereby consolidating the workpiece.
A method of consolidating a workpiece, the method comprising:
- providing first and second support tools in a face-to-face, opposing relationship as first and second support tracks having rotatable links;
- disposing at least one susceptor and workpiece between the support tools;
- generating an electromagnetic field, thereby inducing an electric current in the susceptors and heating the susceptors and the workpiece to a processing temperature, the support tools being substantially transparent to the electromagnetic field such that the electromagnetic field is substantially transmitted through the support tools;
- and
- consolidating the workpiece.
A method of consolidating a workpiece, the method comprising:
- providing first and second support tools in a face-to-face, opposing relationship;
- disposing at least one susceptor and workpiece between the support tools;
- engaging at least two transverse edges of the susceptor into electrical contact at a location proximate to the electromagnetic field generator such that a current induced in the susceptors by the electromagnetic field generator flows between the susceptors, thereby inflating a bladder in communication with the transverse edges to urge the edges together;
- generating an electromagnetic field, thereby inducing an electric current in the susceptors and heating the susceptors and the workpiece to a processing temperature, the support tools being substantially transparent to the electromagnetic field such that the electromagnetic field is substantially transmitted through the support tools;
- and
- consolidating the workpiece.
