麻竹制备竹基纤维复合材料的性能初探

Preliminary Study on the Properties of Dendrocalamus latiflorus Munro Bamboo-fiber Based Composites

为了探索利用麻竹制备竹基纤维复合材料的性能,首先利用纤维可控分离技术将麻竹制备成纤维化竹单板,经过浸胶干燥后,采用热压法制备竹基纤维复合材料,并探讨密度对其耐水性能和力学性能的影响。结果表明,采用热压法制备的竹基纤维复合材料的性能较优,已超过重组竹地板标准规定的室外用地板的指标值。随着密度的增加(0.90~1.15g/cm^3),麻竹竹基纤维复合材料的耐水性能得到改善,其静曲强度、弹性模量和水平剪切强度等主要力学性能增强。在应用中可以考虑在保证板材使用性能的前提下,尽量降低竹基纤维复合材料的密度以节约成本。

In order to explore the properties of the Dendrocalamus latiflorus Munro bamboo-fiber based composites,the bamboo was made use of oriented bamboo fiber mats and then made for bamboo fiber-based composites using hot pressing method after dipping and drying.The effect of density on water resistance and mechanical properties of the composites was studied.The results showed that the properties of the composites made from Dendrocalamus latiflorus Munro bamboo tested were superior to the values of the bamboo scrimber flooring outdoor standard.With the increase of the density（0.90~1.15g/cm^3）,the water resistance was improved,and the mechanical properties,such as the MOR,MOE and the horizontal shear strength were improved.In the practice,under the premise of guarantee board performance,the density of the bamboo-fiber based composites should be reduced as soon as possible to save the cost.
