Study Of Uv Curable Rubber-Toughened Epoxy Systems, Abhijeet A. Godbole

Masters Theses

Rubber-toughened epoxy resins are used extensively in various structural applications. Current thermal curing processes limit the possible structural designs and require higher inputs in terms of pressure, temperature and time. UV and electron beam curing offers almost instantaneous curing of even complex structural shapes using minimal inputs. Various formulations were quenched from single phase at high temperatures to various temperatures below the corresponding cloud point temperatures, before being allowed to cool to room temperature. These quenched formulations were then cured using UV and thermal energy. The cured material toughness increases with decreasing particle size by over 150%. The rate of …
