Patent ID: 11584835

Abstract:
A laminated substrate obtained by laminating a carbon fiber reinforced resin substrate (a) containing a carbon fiber and a thermoplastic resin fiber and a glass fiber reinforced resin substrate (B) containing a glass fiber and a thermoplastic resin, wherein a content of the carbon fiber in the carbon fiber reinforced resin substrate (a) is 20% by mass or more and less than 100% by mass with respect to a total mass of the carbon fiber reinforced resin substrate (a), and the carbon fiber reinforced resin substrate (a) has an elongation percentage of from 20% to 150% at a maximum load point in a MD direction at a temperature of a melting point of a resin constituting the thermoplastic resin fiber+20° C., an elongation percentage of from 20% to 150% at a maximum load point in a TD direction, and a tensile stress of 1.0×10−3 to 1.0×10−1 MPa.
