| Abstract: | Fast-growing Chinese-fir was modified with the methyl methacrylate(MMA).The result showed that the permeability of Chinese-fir was excellent with MMA;the mass of modified Chinese-fir increased obviously and the uniform of density profile was better than expected.When the rate of density-gain was 60%,bending strength,hardness of cross section and compressive strength parallel to gain of wood increased by 6.37%,90.77% and 36.32%,respectively.Modified wood dimensional stability improved.Oven drying shrinkage o... |
