Topology and structure analysis of carbon fiber-reinforced polyimide composites

This paper describes the production of carbon fiber / high-performance polyimide prepregs and study prepreg samples quality by scanning electron microscopy, atomic-force microscopy ion-conductance microscopy. The were produced using a laboratory-designed setup impregnation with solution. structure made it possible to establish connection between polymer matrix composition impregnation. Thus, shows that containing aliphatic fragment quaternary atom produces best performance suitable for FDM 3D printing.
