Abstract:Elastic factor of elastic epoxy was investigated by TMA (Thermomechanical Analysis) and DMTA (Dynamic Mechanical Thermal Analysis) as toughness investigation to improve brittleness of existing epoxy resin. A range of measurement temperature of the TMA and DMTA was changed from -20 ℃ to 200 ℃ . When modifier was the rate of 0 phr, 20 phr, and 35 phr, Tg (glass transition temperature) of elastic epoxy was measured by thermal analysis devices. Also it was investigated thermal expansion coefficient (α), Modulus, a… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
