摘要

竹材生長於亞熱帶及熱帶地區，其分佈廣泛，在臺灣已有甚多竹種，其利用在傳統生活上佔有極重要之地位。近年來，竹製品製造受到嚴重之衝擊，為了擴展其新用途，並改善竹材之天然缺點，乃著手於竹塑材之研究。本研究利用苯乙烯與甲基丙烯酸甲酯之混合單體，添加適量染料，注入於麻竹、莿竹、巨竹及綠竹中，利用熱觸媒法製成染色竹塑材，改良其物理、力學性質，其主要結果摘錄於次：1.靜曲強度之改良效果以竹腔向上較佳，其中以莿竹最佳；而竹皮向上者亦有相同之趨勢。2.竹材硬度之改良效果以竹腔較佳，其中以莿竹最顯著，而竹皮亦有相同之趨勢。3.劈裂強之改良效果以麻竹最佳，且四種竹材均真有顯著之改良效果。

Bamboos growing widely in subtropical and tropical zones and there are many species in Taiwan. Ever since antiquity, bamboo has important role in the livelihood. Recent years, because of the sever shock to the bamboo marketing, it is necessary to modify the natural disadvantages of bamboo to be made as bamboo and plastic composites to enhance the value and extending the new utilization of bamboo. The 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 physical and mechanical properties were modified. The main results obtained by this study may be summarized as follows: 1. 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. 2. 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. 3. MA bamboo appeared to have the highest improved effect in cleavability, and all of the four bamboo species appeared to have evident improved effect.
