Abstract: A fabricating method for an armor panel uses a template to position tiles on an adhesive surface. The template includes an L-shaped frame and cells having precise wall thickness. Tiles are fitted in the cells against the surface. The template is repeatedly repositioned so new tiles can be fitted into unoccupied cells to form a desired tile array. A border is placed around the array, forming a cavity. Resin is poured into the cavity. A back plate placed over the array presses against the resin. Excess resin exits the cavity through an interface between the border and the adhesive surface and through a gap between the back plate and border. After the resin cures the border is removed.
