Abstract
Provided herein are composite materials comprising a layup consisting of one or more surfacing sheets comingled with a carbon fiber non-woven mat. The surfacing sheet may comprise polyamide-6 and the carbon fiber non-woven mat may comprise carbon fibers that have been recycled. The surfacing sheets comprise sub-micron scale particles for reducing the thermal expansion coefficient of the surfacing sheets. The resulting layup is suitable for use in the formation of articles, particularly articles requiring a smooth finish absent of defects caused by underlying surfaces having irregular compositions or textures.
