Abstract
Disclosed herein apparatus and associated methods relate to body armor comprising a plate having a ceramic tile bonded to front and back polyolefin layers by front and back pretreated prepreg layers. The pretreated prepreg layers may comprise epoxy resin sheets precooled for storage at 0° F. The polyolefin layers may comprise 940 and 1880 denier extruded polyolefin sheets. The stored cold prepreg sheets may be heated and the hot prepreg sheets used to join the ceramic tile with the extruded polyolefin sheets. The ceramic tile may be bonded to the extruded polyolefin sheets by cooling the ceramic tile, extruded polyolefin sheets and hot prepreg sheets in a −58° F. freezer, forming a cooled bonded plate. A backer comprising stacked plastic sheets may be connected to the plate. The cooled bonded plate may be cured by a curing cycle comprising 260° F. and 120 PSI using an autoclave.
