摘要

本研究之竹材纖維板，以密度0.7 g/cm^3為例說明。自孟宗竹及其竹兩種原料所製造之纖維板，其性質差異不明顯。以孟宗竹外層為原料而製造之纖維扳，具有較大之靜曲破壞強度（約350 kgf/cm^2），以竹節為原料者最低（約200 kgf/cm^2）。濕潤處理後之強度保留率約26-43%。靜電定向排列之抄板方法能提高強度（MOR〃/MOR⊥=1.33; MOE〃/MOE⊥=1.52）。內聚力則以孟宗竹中層為原料之纖維板為最高（約35 kgf/cm^2）。浸水24小時及30日後之厚度膨脹率，差異不顯著（6.1-9.5%）；濕潤處理促使厚度膨脹顯著增加。

For this study, the density of bamboo fiberboard was took example by 0.7 g/cm^3 in explanation. The fiberboard made from Mousou and Madake bamboo showed that the difference of the properties was insignificant. The fiberboard made from Mousou outer layer showed higher MOR (350 Kgf/cm^2) than that from bamboo joints (200 Kgf/cm^2). After wet treatment (2 hrs boiling and 1 hr soaking in room temperature cool water) the strength retained about 26-43% only. The mat forming by orientation method with static electricity could improve on the strength (MOR,,/MOR⊥=1.33: MOE,,/MOE⊥=1.52). The fiberboard made from Mousou middle layer showed the highest internal bond (35 Kgf/cm^2). The bamboo fiberboard soaked in water for 24 hrs and 30 days showed the thickness swelling was not significant (6.1-9.5%), but the wet treatment let the thickness swelling increased obviously.
