大钩叶藤与玛瑙省藤材的主要物理力学性质对比1）

摘要

以大钩叶藤材为研究对象，测得其基本密度值为0．3021 g／cm3，抗压强度值为16．92 MPa，抗弯弹性模量和抗弯强度分别为124．43 MPa和20．46 MPa。并将其与玛瑙省藤材进行比较，以期为大钩叶藤材商业化利用提供基础数据。结果表明，大钩叶藤材的材性较差，直接应用不能满足商业化利用的要求，需对其进行改性研究。%With Plectocomia assamica Grift, we determined the value of basic density of 0.302 1 g/cm3 , the compressive strength of 16.92 MPa, the bending modulus and bending strength of 124.43 and 20.46 MPa, respectively.All these properties were compared with Calamus manan, we provided an effective way for commercial utilization of P.assamica.The properties of P.assamica material are poor , and direct application cannot meet the commercial utilization requirements , so P.assamica needs modification .
