Process feasibility and kinetic analysis of glass fiber‐reinforced vinyl ester/nano‐Al2O3 matrix composites for pultrusion

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, dα/dt = A exp(−E/RT)αm(1 − α)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. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
