竹材宏观自仿生纤维束的拉伸性能分析
Research on mechanical properties of macro-scale self-bionic bamboo fiber bundle
摘要
Abstract
Axial mechanical properties of bamboo fiber bundles with bionic spiral structures were tested in this study. The results showed that the tensile strengths of fiber bundles with non-twisted and uniform structure and those with single-spiral, double-helix A and double-helix B structures were 11.5 ,51. 7 ,52. 2 and 56. 1 MPa,respectively. The spiral structure eliminates the weak points of the fiber bundle and improves the inter-fiber linkage. Meanwhile, the gradual change of the helical angle in different fiber layers can also improve the tensile strength. The tensile elastic modulus of samples with single-spiral, double-helix A and double-helix B structure were 9 659, 5 265 and 4 291 MPa, respectively, meaning better performance of single-spiral structure over double-helix one. Self-bionic spiral structure increases the tensile strength but lowered tensile elastic modulus of bamboo fiber bundles.关键词
