B14 Grip Characteristic of the Sole Material adding plant-opal

Abstract

The effective use of rice-husk presently stands as a priority issue. Rice-husk contains cellulose and silica each 75wt% and 25wt%. This silica is called 'Plant-opal' and has a unique shape. It expected to scratch effect by plant-opal. In this study, the plant-opal that is of high purity seceded from rice-husk and the rubber including the plant-opal was measured about dry and wet grip performance. Cellulose was decomposed by cellulase for plant-opal separation. The sample adding plant-opal had a higher coefficient of friction than no filler sample. Plant-opal content reached an optimum level at 5phr. Coefficient of friction was gone up by the silica component of plant-opal and the unique shape.
