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.
A composite material comprising a layup consisting of one or more surfacing sheets with a carbon fiber non-woven mat,
A composite material comprising a layup consisting of one or more surfacing sheets with a non-woven mat wherein the non-woven mat comprises fibers, wherein the non-woven mat contains 20-40wt % of chopped fibers, wherein the chopped fibers comprise lengths of approximately 5-80 mm, 5-60 mm, 5-40 mm, 5-15 mm, 5-10 mm, or 10 mm.
A composite material comprising a layup consisting of one or more surfacing sheets and a carbon fiber non-woven mat,
