Abstract

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
