The presence of the magnetic particles may cause the resin substrate to form bristle-like filaments in areas that the resin substrate overlays the one or more magnets.

Composite material system including elastomeric, ceramic, and fabric layers

According to exemplary inventive practice, ceramic powder or slurry is selectively deposited at many discrete locations on each of many fiberglass fabric substrates. The sizes and/or shapes of the ceramic deposits vary among the substrates. The substrates are selectively ordered and stacked so that perpendicular through-plane alignments of respective ceramic deposits form selected three-dimensional geometric shapes. The resultant stack of substrates, characterized by many three-dimensional ceramic inclusions, is impregnated with an elastomer or an epoxy that binds the ceramic-deposited substrates together, resulting in a finished composite product. Inventive composite structures can be multifariously designed and embodied to afford selected ballistic and/or structural and/or electromagnetic qualities. Another mode of inventive practice provides for incorporation of the above-described inventive composite product as a layer in a multilayer composite system that also includes a high strain-rate-sensitivity-hardening polymer layer, a hybrid composite fabric layer, a ceramic layer, and a polymeric ballistic fabric layer.
