Poly(ether ether ketone) (PEEK) composites were made by impregnation of continuous carbon fibres with aqueous suspensions of PEEK particles made by a novel precipitation process. These particles were suspended in aqueous solutions of ammonium salts of polyamic acids which performed two essential roles: as a polymeric dispersant and as a binder at the fibre-matrix interface. The resulting composite panels had properties that were comparable in some cases to those of commercially available PEEK composites. Fracture surface analysis from unidirectional panels suggests that the miscibility of the matrix and binder affects the failure mode at the fibre-matrix interface.
