PROBLEM TO BE SOLVED: To provide a composite material which has a short molding time and excellent balance between rigidity and strength since a matrix is a thermoplastic resin.SOLUTION: There is provided a carbon fiber-reinforced thermoplastic resin composite material which has a layer (I) containing a carbon fiber (A) oriented in one direction and a thermoplastic resin (C-1) and a layer (II) containing a carbon fiber (B) oriented in one direction and a thermoplastic resin (C-2). In the carbon fiber-reinforced thermoplastic resin composite material, the carbon fiber (A) is a continuous carbon fiber, an average fiber length of the carbon fiber (B) is 5-50 mm, any one of the surface layers is the layer (I), and the carbon fibers (A) and (B) are polyacrylonitrile-based carbon fibers.SELECTED DRAWING: Figure 1 |
