This paper is dealing with the influence of processing parameters for manufacturing of steel–carbon-fiber-reinforced-plastic
(CFRP) hybrid plates by using the one-shot-hybrid resin-transfer-moulding (OSH-RTM) process. A design of experiments
study was carried out. The quality of the manufactured parts was quantified by the bending modulus, the apparent interlaminar
shear strength (ILSS), the maximum deflection and the density of the CFRP. The following changeable processing parameters
were chosen: mould temperature, resin temperature, change in mass flow and maximum injection pressure. It is shown that
the mould temperature and the change in mass flow show significant impact on the flexural modulus, density and maximum
deflection of the plate while there is no significant impact on the apparent ILSS. Furthermore, the interaction between the
mould temperature and resin temperature is having an influence on the flexural modulus and density.
