竹质工程材料的制造方法与性能

竹质工程材料是利用性能优良、可迅速再生的竹子为原料制造而成。主要的产品有: 竹集成材、竹层积材和分级竹丝复合材料。在竹子生长、采集、加工、制造、使用和产品的废弃过程中, 消耗能源少, 无污染, 是一种高性能的环保材料。与其它工程材料相比较, 其最大的不足在于材料的均齐性。需要采用多种方法提高材料的均齐性, 包括竹材的分级、规则化的加工、浸胶、定向预压、铺层组坯等工艺技术, 以及采用规范的质量控制和检验方法, 才能制造出符合要求的工程材料。其物理和力学性能良好, 可广泛用于风轮叶片、船舶等领域。 

Processing and properties of engineering bamboo products

Made from the quickly renewable and high performance bamboo as raw material, engineering materials of bamboo have three productions, glued bamboo sheets, laminated bamboo slices and graded bamboo filament composites. In the whole period of growth, collecting, processing, making, using and discarding, the materials used less energy, and caused no pollution. Compared with other engineering materials, the bamboos are badly uniform and regular. So, many ways can be used to improve the uniformity and regularity, such as grading, regular processing, soaking resin, orienting, laminating and pressing, controlling quality, and inspecting. Engineering bamboo materials have high mechanical properties, and can be used in wind turbine blades and boats.
