纸质构件力学性能试验研究

TESTING ON MECHANIC PROPERTIES OF PAPER MEMBERS

  • 摘要:  对铅化纸制作的纸杆和纸带进行了力学试验, 分析了其力学性能, 结果表明:纸杆应力应变曲线存在线弹性段, 弹性模量主要集中在200\sim400\,MPa, 并具有一定的离散性. 而纸带抗拉曲线呈明显的非线性特征, 极限拉应变主要集中在0.015\sim0.025之间, 纸带的粘结状态对试件的极限拉应变有较大的影响.

     

    Abstract: The experiment aim to analyze the mechanic properties of paper members was done with pole and belt made by lead paper, It shows that there is a elastic liner segment in the stress-strain curve and the elasticity modulus are separated from one another but mainly between 200MPa~400MPa. The property cure of the paper belt is nonlinear. The large ultimate strain is between 0.015-0.025.The state of bonding has an significant effect on Ultimate Tensile Strain of the belt. The experiment result is helpful to the optimum design of paper structures.
