Was found that the hardness of the spike pin can be adjusted over a wide range depending on the blending amount of the thermosetting resin and the processing temperature. Furthermore, the plant-based raw material used in the present invention is in a finely divided state, for example, powdery,

It is possible to improve the braking performance on an icy road without causing the braking. On the other hand, braking performance on ice is equivalent to that of conventional metal spike pins such as steel, but durability is equal to or higher than that of metal spike pins due to the excellent wear resistance of hard porous carbon materials obtained from plant-based materials. is there.

マテリアルであるという特長も有する。According to the present invention, by adjusting the amount of the thermosetting resin used and the heat treatment temperature (firing temperature), the Vickers hardness is 30 to 1500, which is softer than the asphalt road surface and harder than the icy road surface. Can be adjusted in a wide range, preferably 200 to 1000. In addition, according to the present invention, since about 75% by weight of the spike pin material is a natural material, the spike pin is also an eco-material that has less influence on the environment such as the human body than conventional metal or plastic spike pins.
