Ceramic-polymer composites for ballistic protection

Armour systems require advanced solutions, relying on a combination of materials of different natures to provide adequate ballistic protection and weight saving. For the first time in the present study composite layered systems based on monolithic armour ceramic tiles joined with polymer infiltrated ceramic foams have been designed and evaluated for lightweight ballistic protection. Open cell silicon carbide foams of various cell sizes infiltrated with thermosetting or elastomeric polyurethane were used for this design. The ballistic test results are discussed taking into account the morphological characteristics and main physical properties of the materials used (facing ceramic tile, ceramic foam and polymers), as well as test conditions. The proposed design may be considered for structural and vehicular protection solutions, including blast protection. © 2006 Institute of Materials, Minerals and Mining.
