摘要
重组竹是一种新型的生物质纤维增强复合材料,前期研究表明该类材料的静态力学性能存在一定的随机性。本文针对重组竹的抗拉强度进行研究,采用标准拉伸力学试验确定重组竹的抗拉强度,并对试验结果进行数理统计分析。研究结果表明,重组竹的抗拉强度试验结果呈现明显的分散性,同时正态分布以及对数正态分布函数均能对其进行准确拟合,具有较好的工程适用性。
Recombinant bamboo is a new type of biomass fiber reinforced composites.Previous studies have shown that the static mechanical properties of this kind of materials have certain randomness.In this paper,the tensile strength of Reconstituted Bamboo was studied.The tensile strength of Reconstituted Bamboo was determined by standard tensile test,and the test results were analyzed by mathematical statistics.The results show that the tensile strength test results of Reconstituted Bamboo show obvious dispersion,and the normal distribution and lognormal distribution function can accurately fit it,which has good engineering applicability.
