Heat-resistant carbon fiber composite materials based on fusible oligoimide

In this work, oligoimide powder binders of the IDA type based on 4,4’-’oxydiphthalic anhydride and bis-(4-acetamido)diphenyl oxide with different molecular weights were obtained. CFRPs were obtained by electrostatic spraying of a powdered oligoimide binder onto a carbon fabric, followed by high-temperature calendering and hot pressing of prepregs. The thermal and mechanical characteristics of the obtained carbon composites are determined.
