Corrosion of fibreglass in aqueous solutions of different concentrations of H2SO4 or NaOH for different intervals of time was studied at room temperature and at 50 deg C. The effect of irradiating glass samples with 1, 3 and 7 Mrad (using 60Co as a source for y-rays) on the corrosion rate was also investigated. Results showed that fibreglass corrosion was higher in the acid than in alkaline solutions. Corrosion increased at higher temperature, with y-irradiation augmenting the observed corrosion of the glass in both acidic and alkaline solutions.
