This Research deals with the mechanical and physical properties of composite boards made with soft wood fiber and two types of Sugi particle (shaving and strand) in order to develope high performance wood based boards.Firstly, the effect of mixing ratio of wood fiber and two types of particle on the properties of homogeneous boards were evaluated. Modulus of elasticity of homogeneous boards increased with increasing mixing ratio of particle to fiber, especially at fiber-strand boards. However, no significant differences were found among the bending strengths for fiber board, fiber-shaving board, fiber-strand board and the mixed boards. Bending property retention increased with increasing mixing ratio of wood particle. On the contrary, there was no consistent differences in internal bond strength among boads.Three-layr boards that consisted of fiber elements as face layrs and particle elements (shaving or strand) as a core layr showed remarkably higher bending properties compared with t … More hose of the three-layr board hving the inverse element construction. This was due to the formation of high density surface layrs during hot pressing when fiber was used un the face layrs.Next, flexural creep behavior of ten laboratory composite boards made with soft wood fiber and Sugi particles was evaluated under natural interior climate. In this study, three replicates of each board were used at each stress level. Stress level ; 10,20,30,40%, Loading time ; max.290h, Test term ; May 10-Aug.10 in 1994.As for relative creep of homogeneous boards made with wood fiber and particle, relative creep increased with increaing mixing ratio of particle to fiber, and especially at fiber-stand board. This is because large flakes with their large contact areas provide sufficient horizontal shear strength between particles.Three-layr boards consisted of particle elements (shaving or strand) as face layrs and fiber element as a core layr showed remarkably lower relative creep than MDF and the three-layr board having the inverse element construction. This is completely oposite construction to short-term bending property.As for the effect of stress lebel on the creep behavior, which was measured on the three kinds of composite boards made with the same materials (50 percent fiber and 50 percent shaving), the three-layr board made with fiber for the surfaces had a tendency to increase in relative creep more sharply than the other two boads with an increasing stress level.The strongest correlation was observed between the relative creep and the bending properties ratio (MOE/MOR) of tested composite boards. Then it appered to esttimate the relative creep of composite boards from their bending properties ratios. Less

为了开发高性能人造板，本研究以软木纤维和杉碎料（刨花和刨花）为原料，研究了其复合板材的力学性能和物理性能。均质板的弹性模量随着颗粒与纤维的混合比的增加而增加，特别是在纤维刨花板中。而纤维板、纤维刨花板、纤维刨花板和混合板的弯曲强度之间没有显著差异。弯曲性能保持率随刨花掺量的增加而增加。相反，板材之间的内部结合强度没有一致的差异。由纤维单元作为面层和颗粒单元（刨花或刨花）作为芯层组成的三层板材显示出比纤维单元作为面层和颗粒单元（刨花或刨花）作为芯层的三层板材更高的弯曲性能。 ...更多信息 具有反向元件结构的三层板的软管。这是由于在热压过程中，当纤维用于面层时，形成了高密度的面层。其次，在自然室内气候条件下，对10种由软木纤维和杉木颗粒制成的实验室复合板的弯曲蠕变行为进行了评价。在本研究中，在每个应力水平下使用每个板的三个重复。压力水平; 1994年5月10日至8月10日，加载时间10，20，30，40%，最长290 h。木纤维刨花板的相对蠕变随刨花板与纤维混合比的增大而增大，尤其是纤维板。这是因为具有大接触面积的大薄片在颗粒之间提供了足够的水平剪切强度。由作为面层的颗粒单元（刨花或原丝）和作为芯层的纤维单元组成的三层板显示出明显低于刨花板和具有反向单元结构的三层板的相对蠕变。对于应力水平对蠕变性能的影响，本文对三种相同材料的复合板进行了测试（50%纤维和50%剃须），这三个-随着应力的增加，表面用纤维制成的层板的相对蠕变比其他两种板增加得更快在测试的复合板的相对蠕变和弯曲性能比（莫伊/莫尔）之间观察到最强的相关性。然后由复合材料板材的弯曲性能比来估算复合材料板材的相对蠕变。少
