A method for forming a thermoplastic panel comprisestacking together a plurality of plies of material comprising thermoplastic resin (302) and fiber (301) to form a skin (310), the plurality of plies of material are tacked together over a substantially planar surface (305);clamping an edge (312) of the skin (310) to a mandrel (320);heating, via a heating element, the skin (310) to a forming temperature;moving a thermoforming apparatus (330) with respect to the mandrel (320);rolling at least one roller of the thermoforming apparatus (330) along the skin (310) in a direction away from the clamped edge (312) of the skin (310) in response to the thermoforming apparatus (330) moving with respect to the mandrel (320), wherein the at least one roller is optionally compressed against the skin (310) via a spring member; andin response to the at least one roller of the thermoforming apparatus (330) rolling along the skin (310), compressing the skin (310) between the at least one roller and the mandrel (320), consolidating the plurality of plies of material, and bending the skin (310) to conform to a shape of the mandrel (320); andcooling the skin (310) after consolidating and conforming the skin (310) to the mandrel (320) to a temperature below a recrystallization temperature of the thermoplastic resin (302).
