固化冷却过程中复合材料参数对其应变的影响

Effect of composite material parameters on its strain during solidifying and cooling process

为有效降低某复合材料固化冷却过程中的应变水平,以某圆柱形复合材料为例,利用有限元分析软件MSC Nastran,研究固化冷却过程中复合材料参数对其应变的影响.计算得到复合材料最大von Mises应变值和分布位置,分析弹性模量、泊松比、线膨胀系数、密度等参数对其应变的影响.

a cylinder during soli To reduce the strain of a composite material during solidifying and cooling process efficiently, composite material is selected to study the effect of composite material parameters on its strain difying and cooling process by MSC Nastran. The maximum von Mises strain and its distribution of the composite material are obtained. The effect of parameters on its strain are analyzed, including elastic modulus, Poisson ratio, linear expansion coefficient, density and so on.
