短繊維複合天然ゴムの減衰特性発現メカニズム解明に向けた取り組み

抄録

It is known that damping characteristics are improved by complexing fine particles in a viscoelastic material, however the relevant mechanism is unknown. This study focusses on the strain distribution in the composite material and investigate factors that may affect the change of damping characteristics. The X-ray computer tomography image was obtained with before and after a tensile load applied to the test piece, and we did a research on each factor through image processing. It was confirmed that a local strain occurred from this distribution, and suggested that this may be a factor promoting more energy dissipation.
