℃, Tg is 190℃, heat distortion temperature (tensile strength 18.6kg
/m2) is 175°C, and has excellent toughness and high rigidity as a matrix. In addition, such thermoplastic resins can be formed into a sheet as a molding material, heated and melted outside the mold, and then charged into a mold and molded, which is faster than molding with thermosetting resins. Since it can be molded in high cycles, efficient production is possible. Furthermore, for example, a thermoplastic resin may be used, such as a method typified by a nylon rim, in which reinforcing fibers are placed in a mold, heated to a polymerization temperature, and then monomers are poured and polymerized. Regarding what can be obtained with a nylon rim,
For example, it has less saturated water absorption than regular nylon such as nylon 6, making it dimensionally stable, while it has the characteristics of nylon, which has a large molecular weight and high crystallinity, so it has toughness and absorbs vibrations and shocks. It has properties suitable as a base material for the composite member C, such as excellent properties such as excellent elasticity and fatigue strength.

Composite member C by monofilament, that is, one cord body
can also be formed. Also, the composite member C has a diameter of 0°3
45° to 90° to the trend surface in the range of ~15al
1, preferably at a 90° angle, ie perpendicular to the plane of the page of FIG. If the composite member C is arranged at an angle of 45° or less, the bending rigidity during running will not be sufficient, and grip performance on ice will not be exhibited.

%, the composite member C is more likely to be damaged during running. Although the fiber cords 6 are arranged over the entire area of the composite member C in FIG. 2, they may be arranged only in the ground contact area. In addition to being wasteful, it may penetrate too deeply into the tread rubber, reducing the bottom thickness of the tread rubber and hindering its embedding effect. In addition, as shown in FIG. 3, the flange portion 02, etc.
It may also be constructed using hard rubber or plastic, and the total surface area of the ground contact portion of the composite member C is equal to the tread portion 2.
