This paper focuses on the resin ﬂow characteristics of nanoclay ﬁlled glass ﬁber laminates processed by Vacuum Assisted Resin Infusion Molding (VARIM). Laminates with varying quantities of nanoclays (0–5 wt.%) were prepared and the effect of these nanoclays on the epoxy resin ﬂow characteristics was studied. It was found that the ﬂow rate of resin continuously decreased as nanoclay content continuously increased. The reduction in the ﬂow rate was attributed to the rate of change of curing and the subse-quent change in viscosity of the nanoclay ﬁlled resin. Analysis of infusion process by Darcy’s law show that the permeability of the ﬁber decreased in the nanoclay ﬁlled resin system. Nanoclay ﬁlled laminates show improved static and dynamic mechanical properties than that of unﬁlled resin composites.
