中文摘要 | 研究係探討柳杉,杉木及台灣杉等三種造林旋切單板(2 mm及4 mm)製造單板層積板(LVB)之各種強度性質。LVB分為A type與B type,而面板區分為未含浸與含浸PF,共製成六十種不同結構之LVB。其結果歸納於次;(1)從LVB之靜曲強度與衝擊彎曲吸收能量觀之,A type LVB甚具異方性,但依其MOR值觀之,足夠當作地板材料使用。(2)構成LVB之單板纖維平行與垂直方向的成分比例會影響到該LVB的靜曲強度,衝擊彎曲吸收能量。(3)面板含浸PF之LVB的硬度值會較面板未含浸PF之LVB改善甚多。其改善改應(I. E. )各為柳杉LVB:100%~480%,杉木LVB:100%~460%,台灣杉LVB;25%~122%。 |
英文摘要 | This paper was to investigate that the mechanical strength of various types of laminated veneer board (LVB) made from the rotary cut veneer of plantation timber of Japanese cedar (Cryptomeria japonica), China fir (Cunninghamia lanceolata) and Taiwania (Taiwania cryptomerioides) (2 mm and 4 mm in thickness). The construction of LVB was considered A type and B type, and the face and back veneer were two condition included unimpregnated and impregnated alcohol soluble phenolic resin, and total sixty different constructions LVB were manufactured in this study. The results were summarized as follows: (1) From the view of bending strength and impact bending absorption energy of LVB, The A type LVB characterized the remarkably antisotropic behaviors. However, from the view of MOR values, the LVB could be used as the flooring materials. (2) The bending strength and impact bending absorption energy could be influenced by the ratio of parallel portions to the perpendicular portions to the fiber direction of face and back veneer for the LVB construction. (3) The hardness values could be remarkably improved by the impregnated PF of face and back veneer. The improved officiency values for Japanese cedar LVB, China fir LVB and Taiwania LVB were respectively, 100%-480%, 100%-460% and 25%-122%. |
