摘要
试验以及ANSYS workbench有限元模拟的方法研究了不同铺层的玻璃纤维增强环氧树脂基复合材料在-40~80℃的低温下的弹性模量以及拉伸强度随温度变化的规律。结果表明:有限元模型能够较为精准地模拟不同温度下的拉伸过程,模拟的最大误差仅为8.06%;在-40~80℃的温度下,随着温度的上升叶根材料的纵向拉伸强度降低幅度最大,为27.07%,而层合板的纵向弹性模量只有叶根材料和蒙皮材料变化较为明显。
Using the method of experiment and ANSYS workbench we study the different layers of glass fiber composite material’s mechanical properties under the temperature environment(from-40 to 80℃).Material elastic modulus and tensile strength changes with temperature.Simulation results show that:Finite element model can simulate the experimental process more accurtely,and the maximum simulation error is only 8.06%.Experimental results show that as the temperature rise of glass fiber composite materials tensile strength were decreased,and the blade root materials tensile strength and the root materials elastic modulus with temperature change is most obvious,which is 27.07%.But,only hub material and skin material′s longitudinal elastic modulus obviously changed.
