Author Hideharu Yamaguchi,Toshiyuki Ito,Tsukasa Tomabechi
Summary The purpose of this experimental study is to make the characteristics now sliding c1earĀEĆusing PTFE-Coated glass fiber fabric (Type A ) of the membrane structure. This experiment was examined by controlling an interposition of moisture on the static sliding friction and kinetic sliding frictionĀEĆusing five types of PTFE-Coated glass fiber fabric( Type A) respectively. Farther, using the results of controlling of moisture on the static sliding friction and kinetic sliding friction. study on the relation of the Type-A the surface roughness and the contact angle was done. As the resultĀEĆit became clear that PTFE-Coated glass fiber fabric( Type A) is effective of snow sliding when there is less moisture between The surface of the roof and the snow on it. Different from other roof materials. And PTFE-Coated glass fiber fabric (Type A) is il10uenced by the moisture existing between the surface of the roof and the snow on it. ThereforeĀEĆit is necessary to study fully the ways of giving and controlling of energy on the snow sliding.
