Abstract (en)
A method for producing a carbon fiber composite layer having high strength, comprising steps of: providing two carbon fibers layers (31,32) having fibers (310,320) in parallel with each other and disposed in a stacked form; and heating and pressing the two carbon layers (31,32) simultaneously to form the carbon fiber composite layer. <IMAGE>
