In this paper, several review studies with regards to the rheological study of polymers for both thermoset and thermoplastic are presented. The main aim of this paper is to conduct a comparison analysis to choose and determine the most suitable methods via experimental, theoretical and/or modeling works with regards to the thermoset based per-impregnated reinforced composite. This study focuses on observing various aspects for selecting the most appropriate methods to carry out the experimental and modeling works, including identifying any limitations before the designing of the experiments. It is also aimed to identify the most appropriate model considering the reaction behavior of the thermoset resin under different curing cycles and processing conditions, mainly with regards to the effects of viscosity and temperature changes on the resin impregnation behavior during processing. A few suggestions and recommendations are also presented based on the case studies and their methods chosen. The final selection of the methods to be applied for the experimental works and theoretical/modeling works is also concluded here as the one of the outcomes.
