いた。(Prior Art) As a conventional automobile interior material, as described in Japanese Utility Model Publication No. 57-13314, a base material such as a resin board or a polystyrene board formed in a predetermined shape is laminated on a fiber knitted woven fabric, a non-woven fabric or the like. However, since these are usually made of synthetic fibers, they are strong.
The g / d was not less than 60% and the elongation was not less than 60%, and it was difficult to cut the fibers after cutting, such as finish cutting, and therefore, the man-hour at the time of cutting was extremely troublesome. Moreover, after cutting, the fiber remains at the end of the set, resulting in deep fitting, making it difficult to reduce costs and leaving design problems.

成型された複合材に対し行なわれる。The composite thus obtained is optionally put in a mold and subjected to a molding process, and is cut for finishing and the like.
It is performed on a composite material formed in cooperation with a receiving blade by a cutting blade having a normal serrated cutting edge.
このとき、前記繊維強力と伸度によって、繊維の毛羽を
裁断端に残すことなく容易に裁断することが出来、面倒
な毛羽取りもなく良好なデザインが得られる。At this time, due to the fiber strength and elongation, the fibers can be easily cut without leaving the fluff at the cut end, and a good design can be obtained without troublesome fluff removal.
（実施例） 以下、更に本考案自動車内装材の実施例を説明する。(Example) Hereinafter, an example of the automobile interior material of the present invention will be described.
