Cellular solids are materials whose base material does not always occupy the entire solid fraction available. A number of cellular solids can provide blast protection and absorb impact energy, but few perform well resisting blunt object (ballistic) penetration. In this thesis, a method is proposed for fabricating cellular solids from aramid-epoxy composites that can absorb impact energy and resist blunt object penetration. The aramid-epoxy samples were fabricated using wet-layup techniques, with two different styles of Kevlar 49 woven fabric in a variety of orientations. Test sample density ranged from 0.08 0.23 g/cm3. Different lamination orientations, assembly techniques, and bonding adhesives were investigated and assessed for their effect on quasi-static and dynamic crushing. A maximum plateau stress of 1.5 MPa was recorded with corresponding energy absorption of 4.2 J/g; values comparable to commercially produced metal foams. Methods for prediction of mechanical properties are presented/assessed along with suggestions for further improvements.
