Abstract
Abstract:
A transparent bulletproof materials of soda-lime-silicate(SLS) glass has been ballistically tested after impacting by 5.45mm AK-74 steel core projectiles at distance of 50 meters. The thickness of satisfaction on bulletproof test was about 30mm. For application of transparent bulletproof materials, the SLS glass was heated by crystallization and ion exchange. The Vickers hardness, fracture toughness, and bending strength of crystallized SLS glass was about 704Hv, 0.9409MPa∙m1/2, and 452MPa which is about 24%, 31%, 201% higher than parent SLS glass, respectively. The vickers hardness, fracture toughness, and bending strength of ion exchanged SLS glass was about 657Hv, 0.7337MPa∙m1/2, and 791MPa which is about 16%, 2%, 430% higher than parent SLS glass, respectively. Transmittance of heat treated and SLS glass was decreased slightly at the visible range. The results prove that light-weight bullet proof can be fabricated by crystallization and ion exchange technique of SLS glass.
