碩士 === 國立中興大學 === 森林學系 === 83 === This mixture of styrene monomer, methyl methacrylate monomer and dye chemical was applied for the impregnation of MA bamboo, Thorny bamboo, Gigantic bamboo and Green bamboo to be made as dyed bamboo and plastic composites by means of heat catalyst. The modified gross appearance, physical and mechanical proper- ties as well as the factors influence on the effects of impreg- nation were investigated. The main results obtained by study may be summarized as follows: 1. MA bamboo appeared to have the highest improved effect in water excluding efficiency(WEE). The values of antishrink efficiency(ASE) of radial durection was higher than that of tangential direction, and Green bamboo appeared to have the highest improved effect. 2. The inner portions of culm appeared to have higher improved effect in static bending strength, among the four species Thorny bamboo showed the highest improved effect. The outer portions of culm also had the same tendency. 3. The inner portions of culm appeared to have higher improved effect in hardness, and Thorny bamboo was the most evident among the four species. The outer portions of culm showing the same tendency too. 4. MA bamboo appeared to have the highest improved effect in cleavability, and all of the four bamboo species appeared to have improved effect evidently. 5. Gigantic bamboo appeared to have the highest improved effect in the abrasive resistance, and the tested bamboos which had not been treated by artificial weathering treatment, they showing higher abrasive resistance. 6. Thorny bamboo appeared to have the highest static bending strength reservation after artificial weathering test, and MA bamboo showed the highest hardness reservation. The BPC appeared to have higher weathering resistance, therefor, it holding the higher strength reservation.
