A Rheological Study of Fibre Reinforced Composites and the Factors that Affect Rheological Behaviour during Impregnation Process: A Review

Abstract

Rheological behaviour is an important factor affecting the flow behaviour of a fluid and many aspects related to this, mainly in the manufacturing process of fiber reinforced composites, either for Newtonian fluids or non-Newtonian fluids. During impregnation process, the viscosity changes with temperatures and their strain rate, has influenced the resin flow behaviour during curing process. In this paper, a review on the rheological studies of fiber reinforced composites for both, synthetic and natural based fibers, respectively, are presented. In addition to that, this review paper highlighting a few research studies conducted in literature on the main factors that affecting the rheological quality and performance of the composites. The aims of this review, mainly to capture the trend ranging from the recent five years back and summarize the various studies via experimental, theoretical or modelling works. Furthermore, also aiming to provide an ideal baseline information in the selection of the methods regarding rheological study to ensure better quality of pre-preg product and fibre reinforced composites can be produced in the author’s future work.
