Laminated Panel Manufacture of Two Kinds of Bamboo for Architecture Material and Property Comparison

The manufacture technologies of two kinds of bamboo laminated panel and their physical-mechanical properties have been studied in the paper. The species of bamboo are the D. yunnanicus Hsueh et D. Z. Li in Yunnan Province and P. heterocycla var. pubescens Ohwi in Zhejiang Province. The data are offered in order to provide proof to produce architectural panel by bamboo materials. The results show as follows: Laminated bamboo panel can be produced by the reconstruction technology, and the mechanical properties of the panels reached or even exceeded some pine used in architecture. Comparing the physical-mechanical properties of laminated panel made of two bamboo species, it can be seen that properties of laminated D. yunnanicus Hsueh et D. Z. Li panel were higher than those of laminated P. heterocycla var. pubescens Ohwi panel, but dimensional stability was poorer than the latter. In the comparison of laminated directions, it can be seen that parallel panel had better mechanical properties than crossed pan

Li panel were higher than those of laminated P. heterocycla var. pubescens Ohwi panel, but dimensional stability was poorer than the latter. In the comparison of laminated directions, it can be seen that parallel panel had better mechanical properties than crossed panel, and can be used for bearing parts in building such as I-beam and column, while the laminated panel with orthogonal direction can be used as less or non-bearing components such as wall, roofing and flooring boards. Compared with the P. heterocycla var. pubescens Ohwi panel, the aging characteristic of the D. yunnanicus Hsueh et D. Z. Li laminated panel was poorer. It shows that physical-mechanical properties of laminated P. heterocycla var. pubescens Ohwi panel are more stable.
