| 摘要: |
| 为了研究复合材料层板结构在固化过程中的温度场与固化度场分布情况,对ABAQUS子程序进行了二次开发,构建了不同固化动力学方程的子程序模块,实现了层合板固化过程的三维数值模拟。通过算例验证,所建立的数值分析方法能精确求解固化过程中的温度场和固化度场。基于该方法,进一步讨论了层合板边界条件、厚度、升温速率对温度场和固化度场的影响。上述研究方法具有较强的适用性,对改善固化工艺参数,控制结构固化变形具有一定的指导意义。 |

| Abstract: |
| In this paper, three-dimensional numerical simulation of the curing process of composite laminates is realized with ABAQUS subroutine secondary development method. Being verified by two examples, this method can predict coupled temperature field and degree of cure field relative precisely in the curing process. Moreover, the influence of boundary conditions, thickness and heating rate on the temperature field and the degree of cure field are discussed with this method. When curing kinetic equations are different for different types of composites, just program with the Fortran language on the basis of ABAQUS subroutine according to the corresponding equations; this shortens the program cycle. The applicability of this method is universal and it provides meaningful guidelines to refine the curing process parameters. |
