The research on vibration damping of epoxy resins holds great potential, as it addresses the ongoing risks posed by vibration environments to the maintainability and suitability of materials in diverse applications. The addition of fillers emerges as a key method to transform epoxy resin properties, offering potential benefits.

This research focused on zirconium tungstate, a ceramic powder with a negative thermal expansion coefficient. It was meticulously added to three epoxy resins, each based on a bisphenol A diglycidyl ether epoxy and three different amine hardeners. The zirconium tungstate was introduced in varying percentages (0.1, 0.5, and 1 wt.%) to the epoxies, and the effects on the epoxies' thermal expansion, glass transition, and vibration damping properties were rigorously studied in both low-frequency and high-frequency domains, up to 2KHz.

The glass transition temperature of the epoxies showed a decreasing trend with increasing filler percentage, which is a typical finding when adding fillers to epoxy resins. The thermal expansion coefficient (CTE) provided interesting results. There are two CTEs for the epoxy resins. One below and one above the glass transition (Tg), the CTE below Tg highlight a suppression of the epoxies CTE, however above Tg, the CTE increased with increasing filler content. Vibration damping in the low and high-frequency domains posed new challenges initially through the use of time-temperature superposition supported by Kramers-Kronig relations to validate the shift curves, which saw the shift factors relate to the Williams-Landen-Ferry model. A high-frequency set-up was created to explore the epoxy resin vibration responses up to 2KHz, in line with ASTM E756-05. The storage modulus increased with increasing filler content at room temperature. Overall, this thesis explores the relation of the zirconium tungstate filler to the epoxy resin focusing on the vibration damping properties.
