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.
