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.

Abstract: In an embodiment, the present disclosure pertains to a method of recycling that includes applying an electromagnetic field to a composite material having carbon fiber therein, heating the composition, degrading a matrix of the composite material, and recovering the carbon fiber from the composite material. In an additional embodiment, the present disclosure pertains to a method of non-contact recycling that includes applying an electromagnetic field to a composite material having carbon fiber therein with an electromagnetic applicator via at least one of direct current or alternating current, heating the composition, degrading a matrix of the composite material, and recovering the carbon fiber from the composite material. In some embodiments, the electromagnetic field is applied in a non-contact manner. In some embodiments, the heating is locally induced heating that includes increasing the temperature inside the composite material via an inside-out method thereby initiating pyrolysis within the composite material.
