ニトリルゴムの圧縮歪(第1報)

Abstract

When the ideal elastic substances are used as orifice of liquid or gas in a closed chamber, these amounts of outflow are changed regularly according to the change of cross section of the orifice due to the compression. But when rubber (natural or synthetic) are used for it, the instant deformations due to the compression are followed the deformation by creep and the amounts of outflow changes with time. Hence the combinations of rubbers and other sub-materials must be controlled as instant deformation to be large and as creep deformation to be small. We researched about the combinations of synthetic rubber (Nitrill gum) and other sub-materials adapt to this object.
