It was found that carbon with an extremely steady characteristic can be obtained by baking the furan resin, one sort of thermoset high polymer in the condition of 3-4°C/h up to 200°C and 7-8°C/ h above 200°C respectively in N2 gas and He gas atmosphere. Relatively few researches have been done so far of the high molecule carbon as a bulk material such as the one we did. The application as an industrial material can be expected by further elucidation of physical properties. We are trying its material as one or two of applications, the one is useful for long life impact printing types as the high-speed computer-printer. In this report, we will report on the relationship between the baking temperature and the surface hardness as well as the baking temperature and superior wear resistance as part of study for the improvement and completion of the material. The surface hardness of carbonized furan resin is reinforced in proportion to the baking temperature from 500°C to 1250°C, and indicated the maximum at 1250°C. Its hardness indicated 429 at HV, and 449 at HK. Wear resistance is increased between 500°C-1250°C.
