Effects of Post Cure Conditions on Thermal Characteristics of A1$_2$O$_3$ Filled Epoxy Resin Composite System

A1$_2$O$_3$ 충전된 에폭시 수지 복합재료계의 후기 경화조건에 따른 열적특성

The effects of post curing conditions on thermal properties of alumina filled epoxy resin system DGEBA/MDA/SN were investigated. As the post curing time increased at 15$0^{\circ}C$, the glass transition temperature increased from 121 to 124, slightly. As the heating rate increased, high thermal decomposing temperature (T$_{d}$) and most decomposing temperature (T$_{p}$) increased. For the case of post-cured system at 15$0^{\circ}C$ for 4 days showed lower values than virgin system. At the post curing condition the system must have been thermally degraded.ded.
