It is essential to produce cost-efficient components to be competitively viable in today’s industrial society. A better component quality through process optimisation has therefore also a high priority for the fiber-reinforced plastics (FRP). The biggest impairement to the component quality is the shrinkage of the resin matrix, by which means it comes to a distortion of the FRP component. That is why the rate of shrinkage has, as it were, the greatest need of improvement. That is the reason why this bachelor thesis is dedicated to the effects of shrinkage by thermosetting resins and their influence by exterior factors. The impact of the time-temperatur-setting on the volume shrinkage was examined with the aid of experiments. Based on those an optimised process control was developed, which is aimed at an isothermal curing process and a minimised physical shrinkage. The process control was adjusted on the specific curing behaviour and was conclusively tested by producing fibre-glass reinforced plastic components using the resin transfer moulding process.
