Outline of Final Research Achievements

It was found that the loss factor of fiber composite greatly changes with the strain amplitude, and the strain amplitude dependence becomes stronger when the strain amplitude direction and the longitudinal direction of fiber particle are close. A dynamic model for fiber composite rubber was constructed. This model assumed that dynamic friction force is proportional to the square of the strain amplitude. The loss factors show good correlation with the recalculated and experimental results; the loss factor can be expressed assuming that the energy dissipation amount owing to the slip is proportional to the square of the strain amplitude.
