A new matrix resin system, consisting of a commercially available cyanate ester, an oligomeric phenylethynyl terminated imide and a compatibilizer for both systems is used for the manufacturing of CFRP laminates by LCM processes. The solubility of the polyimide within the cyanate ester as well as the physio-chemical and mechanical properties of the unreinforced resin in the cured and uncured state are determined using various characterisation techniques. Based on these investigations, the optimum process conditions for the manufacturing of CFRP structures are determined. The thermal and mechanical properties of the CFRP laminates manufactured by handlaminating and VARTM are determined. The manufactured CFRP laminates show very good thermal and mechanical stability up to temperatures of 250°C over a longer period of time.
