摘要：根据混杂复合材料理论,探讨将几种不同单元形态的木材:木束、木刨花和木纤维与重组竹的基本单元——竹束,采用均匀混杂方法制备增强型重组竹结构材料的可行性,研究木束-竹束、木刨花-竹束以及木纤维-竹束的混杂比对增强重组竹结构材抗弯性能的影响。结果表明:与重组竹相比,当刨花-竹束以及纤维-竹束混杂比分别为10%、5%时,在垂直加载和水平加载方向上竹木复合重组结构材料的静曲强度和弹性模量综合增强效果最为明显,而随着木束-竹束混杂比增加,木束增强重组竹结构材料的弹性模量和静曲强度呈现先下降再上升的趋势,当混杂比为33%时负增强效应最大。
The feasibility of preparation of wood-reinforced bamboo reconstituted engineering material was explored. According to composite material theory, bamboo tress （mean cross section area of 8.91mm2 ,length of 45cm）as basic element was evenly mixed with 3 types of wood unit（bunch, shaving and fiber）to prepare bamboo/wood composite reconstituted engineering material. The influences of wood unit type and mixture ratio of the wood unit to bamboo tress on bending properties of the material were studied. The results showed ： compared to unreinforced bamboo reconstituted material, general improvement of bending properties of bamboo/ wood composite reconstituted material under vertical and horizontal loading was the most obvious when mixture ratio of wood shaving to bamboo tress and wood fiber to bamboo tress was 10% and 5 % respectively , while MOE and MOR of bamboo reconstituted material reinforced with wood bunch showed a increasing tendency following initial decreasing with increase of mixture ratio of wood bunch to bamboo tress, and presented a minimum at the ratio of 33%.
