Thermo-mechanicalbehaviors of epoxidized vegetable oils-modified epoxy resins |
| 초록 |
Epoxy materials were prepared from diglycidylether of bisphenol-A (DGEBA) and epoxidized vegetable oils (EVO), epoxidized soybean oil and epoxidized castor oil, with a thermally latent initiator. The effects of EVO content on the thermo-mechanical properties of EVO-modified DGEBA epoxy resins were investigated using several techniques. Differential scanning calorimetry indicated that the cure reaction of the DGEBA/EVO systems proceeded via two different reaction mechanisms. Single and composition-dependent glass transition temperature (Tg) were observed for the systems after curing. The experimental values of Tg could be explained by the Gordon-Taylor equation. The thermal stability of the systems decreased as the EVO content increased. The coefficient of thermal expansion of the systems was found to increase linearly with increasing EVO content. |
