竹木复合材料的研究

Study of Bamboo and Wood Combination Material

竹木复合材所用原料为毛竹、杨木夹板。其中,组坯方式按年份分为两年、三年和四年三种,毛竹经过碾压机碾压成竹帘后再与杨木夹板进行混合铺装。本实验主要研究不同年份、不同摆放方向和不同厚度的竹帘对竹木复合材的抗弯强度、抗弯弹性模量和平面抗拉强度的影响,结果表明,抗弯强度、抗弯弹性模量受年份和竹帘厚度的影响比平面抗拉强度所受的影响要小;9mm竹帘的竹木复合材料的平面抗拉强度受不同年份竹材的影响明显。

The material of bamboo and wood combination in the study is bamboo, poplar plywood. We respectively press 2, 3 and 4 year-old bamboo chick onto both sides of poplar plywood. We mainly studied the different influence of bending strength, MOE, flush tensile strength of bamboo was caused by different year-old and thickness of bamboo chick. The results show that the different influence of bending strength and MOE by years and thickness of bamboo is more than flush tensile strength, flush tensile strength of bamboo and wood combinantion was refected obviously vary with different year of 9 mm thick bamboo chick. So, In the production, we should note more on the way of arranging in pairs of different years and thickness bamboo, for it will reflect a lot on physical mechnics performance of bamboo and wood combination.
