**Abstract**
 Liquid composite moulding is used to manufacture automotive structural composites, and epoxies have been used in vehicle mass production programs. N order to meet the automotive processing and performance requirements, it is necessary to optimise the moulding cycle times. This necessitates an understanding of the curing behaviour of the resin. This study, therefore, examines the curing behaviour of a dimethyl imidazole catalysed diglycidyl ether of bisphenol A-methyltetrahydrophthalic anhydride resin system using isothermal data obtained from differential scanning calorimetry. The system was selected as a potential automotive liquid moulding resin based on its favourable moulding characteristics and thermomechanical properties. The kinetic data were analysed using both n^th order and autocatalytic kinetic models. The results indicated that the epoxy curing process could be described satisfactorily by Kamal's four-parameter generalised autocatalytic model, modified with an exponential function of conversion defined as the diffusion factor. 19 refs.
