Carbonization behavior and density dependence of bending strength were observed onwoods and resin-impregnated woods through heat treament. Soft and hard woods were selected as the samples to which furfuryl alcohol resin was applied. The bending strength of woods were the lowest at heat treatment temperature (HTT) of around 400·Z, which was the same tendency as that for furfuryl alcohol resin. The resin impregnation did not make bending strength increase but volume shrinkage reduce. The relationship, σ=apn was recognized between the bending strength (σ) and the bulk density (p) at each HTT for all the woods examined. Also, the relationship, σ =bpm existed for each wood heat-treated at various HTTs. The exponents n and m were estimated 1.3 and 8.5, respectively. The factors a and b were dependent on HTT.
