Abstract
The need for the resin to flow over long distances through a preform of complex structure is unique to liquid composite moulding (LCM) in comparison with other composite manufacturing methods. However, an extensive literature on the general topic of flow through porous media exists and is helpful for understanding the effects of geometrical complexity on flow behaviour [1–3]. A brief summary of the salient points of the general literature will serve as an introduction to the historical problem of measuring the critical parameters required to characterise the flow of resins into a mould containing a preplaced reinforcement preform.
