Abstract
This study deals with the system of texture grinding on sliding surface of ski. PE (Polyethylene) is used for the material of sliding surface because it is well balanced with low friction, macinability and price. To reduce friction, fine grooves called "structure" are carved on sliding surface. In this study, it calls "Texture". Texture is thought to control the amount of water that is generated by frictional heat between sliding surface and snow surface. By examining frictional heat, mechanism of moisture generating is shown and fundamental phenomenon toward optimization of texture is obtained. The state of generating water varies greatly by the conditions of sliding. Moreover, some experimentation about water repellence and measurement of coefficient of friction are made. Differences of water-repellency and coefficient of sliding friction by the difference of texture are detected.
