The consolidation and curing history during the processing of composite materials affects the final properties of a part in various inter‐related ways. In order to improve the quality of composites, these process‐property relations must be understood in detail. Using a computer‐controlled compression molding and data acquisition system, the processing of PMR‐15/C3k composites has been investigated. The process parameters considered were the pressure, the time at which it was applied and the crosslinking temperature. Parts were tested for inter‐laminar shear strength and flexural modulus, and measurements were made for void content and thickness. Full compaction strength, optimum compaction strength and void sensitivity factor have been defined.
