Abstract
We experimentally studied frictional coefficients on surfaces of Dyneema^[○!R] fiber reinforced plastics that were paid attention as new structural materials of superconduction coils. The frictional coefficients on a surface cut by a diamond cutter were measured; the Dyneema fibers were exposed on the surface. We also measured the coefficients on a grind surface of the plastic on which the Dyneema fibers were not exposed. We measured the coefficients on the two kinds of the surfaces at three temperatures (room, liquid nitrogen, liquid helium), and discussed the expermental data.
