ミドロービング材等の合成樹脂製の場合に著しい。However, when an extrusion molding material is manufactured by using an extrusion molding machine having such an extrusion molding portion 1, the extrusion molding material 6 has a base material 61 at the tip portion of the extrusion molding portion 1. After being extruded, the reinforcing material 7 is in close contact with the base material 61 while being sandwiched between the base materials 61, and is pulled by the adhesive force and pushed out together with the base material 61. As a result, the base material 61 and the reinforcing material 7 are too close to each other. On the contrary, there is a problem that the reinforcing effect is weakened, and particularly when the reinforcing material 7 is made of a synthetic resin such as an aramid roving material, it is remarkable.

The base material 61 and the reinforcing material 7 are formed by the method of extending and providing to the outlet of the die 5 attached to the tip of the extrusion molding portion 1.
Since the base material 61 and the reinforcing material 7 are pulled out in a weakly adhered state instead of being drawn out by the adhesive force of the reinforcing material 7, the base material and the reinforcing material are slightly in contact with each other by curing the obtained extruded material. The present invention has been completed based on this finding, finding that original excellent performance can be obtained.
