Fabrication and characterization of short silicon carbide fiber-reinforced PMR polyimide composites
In situ polymerization of monomer reactants (PMR) polyimides are recognized as the state-of-the-art high temperature polymer matrix resins of polymer composites for service temperatures above 300 ℃. Short fiber reinforced polyimide composites are easy to be processed for manufacturing of small and complicated high-temperature components or parts. In this study, short silicon carbide fiber reinforced PMR type polyimide composites were prepared from short silicon carbide fiber and PMR type polyimide matrix resin, which derived from 4,4’-methylenediamine (MDA), diethyl ester of 3,3’,4,4’-oxydiphthalic acid (ODPE), monoethyl ester of cis-5-norbornene-endo-2,3-dicarboxylic acid (NE). The rheological property of the PMR type polyimide matrix resins was investigated. The composites were prepared from the fiber/B-stage PMR polyimide dry prepreg by hot compression molding. The morphology of the composite was observed by video microscope. The results showed that the short silicon carbide fiber-reinforced polyimide composites also exhibited high thermal stability and good mechanical properties.
