石炭酸樹脂の耐摩耗性の研究(第1報)

抄録

In the 1st report we made experiments on the abrasion resistance of phenol resin in the dry state with the Amsler abrasion testing machine. The following six kinds of phenol resins were applied to tests : that is, two kinds of molded products (cotten linter filler and wood flour filler) and four kinds of laminates (canvas base, kraft paper base, asbestos base and plywood.) For comparison's sake, we made experiments also on cast bronze and medium carbon steel. In these abrasion tests, the materials paired with the specimens of the above-mentioned materials were always medium carbon steel and were fixed, while the specimens were rotated at a peripheral speed of 0.5 m/s. Experiments were made till the rubbing distance of about 6 km. And amount of abrasion, frictional moment and temperature were measured. As the results, the superiority of abrasion resistance of phenol resin was cleared.
