Abstract:
The purpose of the present invention is to provide a laminate being excellent in chemical resistance, wear resistance, vibration absorption properties and flame resistance, and having high mechanical strength; and a method for its production. A laminate 1 comprises a fiber-reinforced resin layer 20 which comprises a reinforcing fiber base material and a resin component containing at least 50 vol % of a specific fluororesin, wherein the ratio of the reinforcing fiber base material to the total volume of the reinforcing fiber base material and the resin component is from 0.30 to 0.70, and a specific substrate 10, wherein at least one outermost layer is the fiber-reinforced resin layer 20, and the ratio of the total thickness of the fiber-reinforced resin layer 20 to the total thickness of the substrate 10 is from 1/99 to 30/70.
