Abstract
The present technology provides a carbon fiber reinforced plastic that includes carbon fibers covalently bonded to an energetic polymer and a polymer matrix. Also described is a method for recycling carbon fibers from the carbon fiber reinforced plastic material using microwave energy to separate the carbon fibers from the polymer matrix.
Claims24
A carbon fiber reinforced plastic, comprising:
- a polymeric matrix;
- at least one carbon fiber in the polymeric matrix;
- and
- an energetic polymer interface located between a surface of the carbon fiber and the polymeric matrix,
- wherein the energetic polymer interface is covalently coupled to the surface of the carbon fiber.

A process for recycling carbon-fiber from a carbon-fiber reinforced plastic, the process comprising:
- exposing the carbon-fiber reinforced plastic to electromagnetic radiation to induce localized dipolar heating;
- decomposing the energetic polymer interface;
- and
- separating the decomposed energetic polymer and the polymeric matrix from the carbon fiber to obtain recycled carbon fiber,
- wherein the carbon-fiber reinforced plastic comprises
- a polymeric matrix;
- at least one carbon fiber in the polymeric matrix;
- and
- an energetic polymer interface located between a surface of the carbon fiber and the polymeric matrix,
- wherein the energetic polymer interface is covalently coupled to the surface of the carbon fiber.
