摘要

研究了模压温度、保温时间对聚酰亚胺树脂强度的影响, 并建立了这些工艺参数与树脂强度的数学模型. 研究结果表明, 热压成型过程中的成型工艺会显著影响聚酰亚胺树脂的强度. 当成型温度为 653 K、无压力时的保温时间为 25 min 时, 聚酰亚胺树脂的压缩强度达到最大值. 通过正交中心复合设计, 拟合得到的多元二次方程式可以在研究范围内充分描述聚酰亚胺树脂的压缩强度特性.

Abstract

Influence of molding temperature and duration time on the strength of polyimide were investigated, and a mathematical model was established. The results indicate that the pressing parameters have significant effects on the strength of polyimide. The compressive strength reaches maximum when the molding temperature is 653 K and non-pressure duration time is 25 min. Besides, a fitted quadric multiple equation is obtained with orthogonal central composite design. It can fully characterize compressive strength of polyimide within the research domain.

Key words： polymers; molding; pressing; process parameters; temperature; duration time; mathematical model
