Erosive Wear Assessment of Sandstorm on the Strength Properties of Automobile Glass

In order to assess the extent of sandstorms effect on automobile glass in the area mostly prone to sandstorms phenomena typical of the Northern part of Nigeria, sandblasting tests were conducted in laboratory on a laminated soda lime glass of 300mm x 300mm with standard automobile glass thickness of 4mm each and PVB film of 1mm. The sand particles were projected by sandblasting machine with an air flow speed of 54km/hr (15m/s) and the impact angle was fixed at 900 while the blasting duration and distance of impingement was 60secs, 180secs, 300secs and 60cm, 40cm, and 20cm respectively. The erosion tests carried out show significant drop in impact strength, and flexural strength.
