  • Patent number: 6655730
    Abstract: The problem to be solved is to provide an automobile interior headliner member which is improved in the film forming property of a complex plastic material used as a base material of the automobile interior headliner member, and has high rigidity and excellent heat resistance, size stability and working efficiency upon attachment; and the base material. An automobile interior headliner molding or forming member which is obtained by kneading mica having a particle size of 10 to 100 &mgr;m with a polypropylene resin having a melt flow rate at 230° C. of 3 to 40 g/10 min to obtain the corresponding resin having a mica content of 15 to 40 wt. %, molding or forming the resin into a mica-containing polypropylene sheet of 100 to 300 &mgr;m thick and then stacking this sheet over each of both sides of an expanded polypropylene sheet of 2 to 6 mm thick obtained at an expansion ratio of 5 to 50 times; and an automobile interior headliner member molded or formed from the molding or forming member.
