Vibration Reduction Ability of Polymers, Particularly Polymethylmethacrylate and Polytetrafluoroethylene

摘要

The vibration reduction ability of thermoplastics (PMMA, PTFE, PA-66 and acetal) and of a thermoset (epoxy) was compared by dynamic flexural testing at <-1.0 Hz. Among these polymers, PMMA exhibited the highest loss modulus, while PTFE exhibited the highest loss tangent. A synthetic rubber had an exceptionally low loss modulus, but an exceptionally high loss tangent. Epoxy and acetal exhibited the lowest loss tangent.
