Abstract

In DGEBA/DDM system, the curing specimen are many curing factors which can affect on thermal and mechanical properties. This study was performed to prove the effect on curing specimen prepared by changing of the curing factors which are curing time and temperature of DGEBA/DDM system. As a result on thermal and mechanical properties, flexural strength, modulus and glass transition temperature (Tg) were increased with curing time and temperature were increased. It was found that the optimum curing condition of DGEBA/DDM system cure at $150^{\circ}C$ for 3hrs at equivalent ratio of 1/1.
