Ramesh noted that when it comes to the military environment, one of the most important aspects is kinetic impacts. Ramesh explained that in late 2010 the Army Research Laboratory solicited proposals to establish a Collaborative Research Alliance (CRA)

This includes developing fundamental understand ing in multiscale materials and ultra-high loading rate environments, executing a asic research program, and enhancing and fostering cross-disciplinary and b cross- rganizational collaboration. The MEDE CRA is considering materials that o include ceramics, metals, polymers, and their respective hybrids or composites, but they are not limited to those materials.

The FGP armor effort includes ingot casting technology and a pilot-scale facility at ATC-Pittsburgh, which Heiple noted could have major implications for providing improved protection for armored vehicles. Heiple said that one of the company's current goals is to achieve titanium performance from aluminum at half the cost, and it is also looking at the possibility of developing a monolithic hull structure for combat vehicles.

A few partici pants believed that the Army changes requirements and can be very bureaucratic. In addition, the size of the market drives the technology, and the military is too 1 Even today there are situations where both materials might not meet a desired level of protec tion.

THE MECHANICAL BEHAVIOR OF PROTECTION MATERIALS Vikram Deshpande, Cambridge University, United Kingdom Vikram Deshpande began his talk by explaining that it is possible to develop armor from "sandwich" panels that consist of a honeycomb core panel. These sandwich panels can perform as well as solid panels when subjected to an explosive shock.

He said these represent a new class of "seamless" structures with 3D fiber arrange ments; they have the potential to revolutionize the next generation of vehicle structures but only if the challenges of production scale-up can be addressed to make them affordable.
