DSC thermo-analysis showed that both of epoxy resins and blended resins had an exothermic peak during the period of thermal-scanning due to the curing reaction. Comparison between different kinds of liquefied wood, blending resins that using the liquefied Japanese cedar of LW-C as the raw material would undergo more degree of cross-linking reaction. They released more reaction heat, and formed a more complete cross-linking structure. However, heat treatment could promote an advanced cross-linking reaction of room temperature cured resins. DSC isothermosetting analyses showed that the curing reaction of both epoxy resins and blended resins conformed to Arrhenius kinetic model. The time needed to achieve 95% of curing reaction was shorter for blending resin than that of epoxy resin.
