Abstract:

The University of Delaware Center for Composite Materials UD-CCM is developing the next generation of lightweight hybrid ceramiccomposite armor kits for Marine Corps tactical and combat vehicles. The focus will be on simulating and modeling the performance of ceramiccomposite lightweight armor at seams and corners, and improving the armors performance in these regions. The light ceramiccomposite armor is comprised of composite backings, adhesives, ceramics and covers. This is an expansion of previous research on performance-weight-cost evaluations and center strike experiments and simulations done on these materials. The effort of this modeling and simulation are to down select for appropriate geometries to improve the performance of seams and corners. The tiles will be restricted to the sintered ceramics SiC due to the ability to fabricate SiC into complex geometries. Model ballistic experiments will validate the modeling done in simulation. During this period 1 The effect of tile thickness at varying gap sizes was explored, finding that a center impact DOP can on be achieved If at a gap size of 0.508 mm. 2 In simulation the adhesive layer improves the ballistic efficiency of the target, experimental tests will confirm or deny this. 3 A step ladder seam design was designed and tested, results are positive. 4 Monolithic Aluminum base curve was re ran at 0.2 SPH and compared to ARL data, material properties may need to be adjusted.
