Abstract:	This work presents a process developed to manufacture glass fiber-reinforced vinyl ester (VE)/nano-Al2O3 matrix composites by pultrusion method. The matrix prepolymer for pultrusion in this study was prepared from blends of VE, initiator (t-butyl perbenzoate), and nano-Al2O3. The process feasibility and kinetic analysis of the unidirectional glass fiber-reinforced VE/nano-Al2O3 matrix composites by pultrusion have been investigated. From the investigations of the long pot life of VE/nano-Al2O3 matrix, the high reactivity of VE/nano-Al2O3 matrix, and excellent fiber wet-out of VE/nano-Al2O3 matrix and glass fiber, it was found that the VE/nano-Al2O3 matrix showed excellent process feasibility for pultrusion. A kinetic autocatalytic model, da/dt = A exp(-E/RT)am(1 - a)n, was proposed to describe the curing behavior of glass fiber-reinforced VE/nano-Al2O3 matrix composites. Kinetic parameters for the model were obtained from dynamic differential scanning calorimetry scans using a multiple regression technique. (C) 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
