石炭酸樹脂の耐摩耗性の研究(第2報)

抄録

In the 2 nd report we made experiments on the abrasion resistance of phenol resin in the dry state at various speed with the new abrasion testing machine specially designed, using tubular specimens. The two kinds of laminates (canvas base and kraft paper base) were applyed to tests. As in the previons report, we made experiments also on cast bronze and medium carbon steel. The specimens were rotated at the following five kinds of mean friction speed : that is, 0.33, 0.45, 0.63, 0.98 and 1.35 m/s. And amount of abrasion, frictional moment and temperature were measured. Also we made some experiments to clarify the effect of direction on the abrasion resistance of laminates. From the results obtained in this report, we made some considerations on the abrasion mechanism of phenol resin.
