While transparent ceramic armor provides excellent ballistic protection performance, current technologies to fabricate parts in size and shape required for vehicles makes it unaffordable. This SBIR program will help develop and demonstrate technology to manufacture full-size curved transparent ceramic windows, that meet topic specifications. Feasibility has been shown during the Phase I and the Phase II work will optimize materials, designs and processes; with focus on repeatability and reproducibility. In the Phase II, we will not only manufacture full-size curved windows and supply hardware Deliverables, but also conduct key producibility, production rate, cost and Technology Readiness Level (TRL) analyses. Phase II is targeted to demonstrate technology at TRL 6, commercialization-ready stage.There is a substantial market for curved transparent ceramic windows. While the program is focused on DHS/USSS discreetly armored vehicles, this is a critical requirement for other government agencies including Department of State and Department of Defense. There is also a substantial commercial market opportunity in armored limousines, and Surmet has already been approached by potential customers! Curved transparent ceramic window armor is required for military helicopters under programs such as Future Attack Reconnaissance Aircraft and Future Long Range Assault Aircraft, and Surmet has already done developmental work on such products.
