Influence of Thermal Annealing and a Glass Coating on the Strength of Soda-Lime-Silicate Glass
Abstract
This project investigated the influence that thermal annealing and the addition of a glass coating has on the flexure strength of a soda-lime-silicate glass used in a variety of military ballistic armor applications. A mixture of glass powder and isopropyl alcohol was sprayed onto the tin side of as-manufactured soda-lime-silicate glass plates and on plates with a 10-mm-long scratch created with either a 1- or 10-N scratch load. The glass coating was cured using an annealing cycle of 6 C/min from room temperature to 675 C, followed by a 1.5-h hold at temperature, and then cool down to room temperature at 3 C/min. Plates that were scratched showed a noticeable strength increase following the annealing process; however, the addition of the glass coating did not result in an additional strength increase for the scratched plates.
