摘　　要：随着人们认识的深入,有限元、边界元等数值方法在复合材料工艺力学中的应用日益受到重视,但因其分析过程烦琐而不利于工程人员的使用。根据复合材料制备工艺特点,推导了以复合材料厚度方向物理场分布变化为研究对象的一维差分算法。分析结果表明,一维差分法具有分析简便、计算迅速、精度足够等特点,直观揭示出复合材料内部温度场、固化度场、材料性能等参数的变化,能够快速评估出固化制度、厚度变化等参数对产品的影响。As the deepening of the knowledge,a numerical method such as finite element,boundary element and etc.applying in composite process mechanics has been paid more and more attention.However,the tedious analysis process is discouraged and cannot be popularized to engineers.According to the characteristics of composite fabrication process,a one-dimensional difference algorithm is derived,which focuses on the variation of physical field distribution in the thickness direction of composite material.The simulation results show that the one-dimensional difference method has the characteristics of simple analysis,rapid calculation and enough precision.The variation of temperature field,curing field,material properties and other parameters in the composite are revealed,base on which the effects of curing cycle and thickness alteration of the laminate could be evaluated quickly.
