A possible molding a relatively wide range of heating temperatures, yet provides a manufacturing method for a motor vehicle equipped with material semi-finished product can be obtained a final product having a high rigidity.
A method of manufacturing automobile equipped material semi-finished product, the fiber web core-sheath type composite fiber are integrated, needle-punched, that is three-dimensionally entangled between sheath-core composite fibers each other it is intended. The core component of the sheath-core composite fiber composed of a copolymer of ethylene glycol and terephthalic acid. Sheath component of the core-sheath type composite fiber composed of a copolymer containing ethylene glycol and adipic acid and terephthalic acid. The weight ratio of the core component and the sheath component of the core-sheath type composite fibers, the core component: sheath component = 1 to 3: 1. Core component and sheath component are arranged concentrically. Fibrous web between the core-sheath type composite fibers each other are bonded by softening or melting of the sheath component.
