Title: LAYERED SUBSTRATE AND METHOD FOR MANUFACTURING SAME
Abstract:
A layered substrate in which a carbon-fiber-reinforced-resin substrate (a) including carbon fibers and thermoplastic resin fibers, and a glass-fiber-reinforced-resin substrate (B) including glass fibers and a thermoplastic resin are layered, wherein the content of the carbon fibers in the carbon-fiber-reinforced-resin substrate (a) is 20% by mass to less than 100% by mass with respect to the total mass of the carbon-fiber-reinforced-resin substrate (a), the elongation of the carbon-fiber-reinforced-resin substrate (a) at a maximum load point in the MD direction at 20°C above the melting point of the resin constituting the thermoplastic resin fibers is 20-150%, the elongation thereof at the maximum load point in the TD direction is 20-150%, and the tensile stress thereof is 1.0×10-3 to 1.0×10-1 MPa.
