In this study, Cryptomeria japonica was liquefied in phenol with H2SO4 and HCl as a catalyst. The epoxy resin was synthesized from epichlorohydrin and bisphenol A with the molar ratio of 5/1. Blending resins were prepared by mixing the liquefied Japanese cedar and epoxy resin with weight ratios of 30/100, 50/100 and 70/100, and the triethylene tetramine was added as a cross-linking hardener. The effect of mixing ratios of liquefied Japanese cedar to epoxy resin and amount of hardener added on the reactivity of blending resins and the properties of cured resins were investigated.
