In view of the fact that in spite of the detailed investigations that have been made of the dynamical behavior of plastics since Maxwell and Voigt presented their models, no dynamical model of FRP (Fiberglass Reinforced Plastics) has yet been developed, it is felt required that such a new model of FRP will have to be established. The researches, if they were attempted, would be limited to creep and relaxation of Maxwell or Voigt models. When FRP material is vibrated or is fatigued, such peculiar phenomena are recognized as change in dynamical elasticity under vibration and increase in rigidity under fatigue. These phenomena can not be explained by Maxwell and Voigt models. So we have constructed a dynamical model of FRP with design that internal friction will take place, based upon the fact that FRP consists of two layers of resin and glassfiber. Therefore a slider is involved in the model as vital factor in order to explain these phenomena. In this paper the authors present a new dynamical model with a slider to investigate the peculiarity of the phenomena, which are theoretically interpreted.
