试验以人工林日本落叶松成熟材早材为试验材料,采用植物短纤维力学性能测试仪对日本落叶松单根纤维的纵向力学性能进行了测量。试验采用球槽型夹紧方式,夹持木材短纤维,以及在测试过程中避免木材纤维扭转和剪切,试验测出平均纵向抗拉强度为230MPa,平均纵向弹性模量为1.12GPa,平均断裂载荷为128.37MPa,平均断裂应变为20.52%。 In the experiment, the mature material of Larch (Larix kaempferi) was used as test material, and the longitudinal mechanical properties of Larch (Larix kaempferi) single fiber were measured by the mechanical properties tester. Test using ball-groove clamping, clamping wood staple fiber, and to avoid the wood fiber during the test to reverse and shear, the test measured the average longitudinal tensile strength of 230MPa, the average longitudinal elastic modulus of 1.12GPa, the average fracture The load was 128.37 MPa and the average strain at break was 20.52%.
