摘　　要：将零距拉伸技术和单根纤维拉伸技术应用到藤材研究领域中,初步测试了黄藤材纤维的抗拉强度和弹性模量等力学性能指标。结果表明:通过零距拉伸技术测得的黄藤材纤维的抗拉强度为76.97～200.42 MPa,平均值为157.8 MPa;而通过单根纤维拉伸技术测得的黄藤材纤维的拉伸强度为166.12～880.24 MPa,平均值为540.72 MPa;弹性模量为1.91～11.58 GPa,平均值为4.62 GPa,伸长率为1.22%～17.24%,平均值为8.09%。这两种试验结果产生的差异可能是由于制取的试样不同造成的,但是从微尺度角度来评价藤材的微力学性能是可取的。The study aims to apply the zero-span tensile technology and single fiber to the research field in rattan wood. The tensile strength and elastic modulus of fiber from Daemonorops margaritae were primarily determined. Results showed that the tensile strength of fiber from D. margaritae was 76.97-200.42 MPa, and the mean strength was 157.8 MPa. The elonga- tion, tensile strength and elastic modulus of single fiber from D. margaritae were 1.22% -17.24%, 166.12-880.24 MPa and 1.91-11.58 GPa, and the average values of them were 8.09%, 540.72 MPa, and 4.62 GPa, respectively. The variance of the results was possible due to the difference of the sample, while it is feasible to assess the mechanical properties of rattan wood from microscale.
