Abstract
A method of fabrication processing a pre-preg material includes applying electromagnetic heating to a composition including a fiber and a resin. The electromagnetic heating is conducted with at least one fringing field capacitor utilizing radio frequency (RF) alternating current (AC) and controlling cross-linking of the resin in the composition via the electromagnetic heating.
Claims20
A method of fabrication processing a pre-preg material, the method comprising:
- forming a pre-preg material by combining a fiber and a resin, wherein the resin comprises carbon nanotubes;
- partially curing the pre-preg material by applying electromagnetic heating to the pre-preg material, wherein the electromagnetic heating is conducted with at least one fringing field applicator connected to a radio frequency (RF) source, and wherein the electromagnetic heating comprises matching an impedance of the RF source with the pre-preg material, the at least one fringing field applicator, and cables connecting the RF source with the at least one fringing field applicator;
- and
- controlling cross-linking of the resin in the extruded pre-preg material via the electromagnetic heating of the carbon nanotubes.
