Abstract
A sliding member having anti-frictional and anti-static properties for a tape or film cassette of an audio- or video-tape recorder or a movie projector, comprising a thermoplastic resin containing 5 to 90% by weight of carbon fiber, said member having less than 10.sup.8 ohms of surface resistance and also having a coefficient of dynamic friction of less than 0.2.
Claims5
A sheet-like sliding member having anti-frictional and anti-static properties for use with a tape or film cassette comprising a thermoplastic resin containing 5 to 90% by weight of carbon fiber, and formed so as to have an uneven surface comprising microscopic concavities and convexities with minute projections of carbon fiber on the surfaces, said member having a surface resistance of less than 10.sup.8 .OMEGA. and a coefficient of dynamic friction of 0.07 to 0.15, said carbon fiber having a diameter of 3 - 30 microns.
