PROBLEM TO BE SOLVED: To reduce the cost of an injection mold for a fastening component and further reduce the cost of a single purpose machine or tool necessary for fastening the component by effectively using a general purpose machine such as molding press or injection molding machine. SOLUTION: In a fastening component-integrated interior base material 1, a plurality of fastening parts 4a to 4f are fixed by fusion bonding to a molding substrate 5 containing a thermoplastic resin and a plant fiber by injecting a thermoplastic resin 3 in a mold 2. The molding substrate 5 comprises 50 wt% each of the thermoplastic resin and a kenaf fiber, and by the heat of a melted PP resin therein, the PP resin entwines with an injected PP resin to obtain a strong fusion bonding. The interior base material 1 has a front face 1b which partially has a recessed face 1a at its center but is as a whole a projected face including a curved surface, and a rear face 1d which partially has a projected face 1c at its center but is as a whole a recessed face including the curved surface. The fastening parts 4a to 4f each has a clip shape and are fittingly joined to the front part of a seat. COPYRIGHT: (C)2005,JPO&NCIPI |
