Abstract
This target has a laminated structure of layered matrials. The first layer is an insulating foam which abuts the front face of a metallic foil front electrode. The front electrode has a thickness not exceeding 0.005 inches. Behind the front foil electrode is an intermediate insulating layer that electrically separates the front electrode from the rear electrode. This insulating layer should be thin enough to permit usage of the target with small caliber ammunition. The rear electrode is a substantially rigid metallic screen having a mesh not exceeding 50 mesh. Behind the rear electrode is an insulating layer having a thickness greater than that of the intermediate insulating layer.
Claims16
An electrically responsive target for registering projectile contact which comprises sequentially abutting each other a front electrode, an intermediate insulating layer, and a rear electrode, said front electrode being a metallic foil having a thickness smaller than that of said intermediate insulating layer, said intermediate insulating layer having a thickness and density that permits substantially maximum compression when it is contacted and penetrated by a projectile, said rear electrode is a metallic screen having a tensil strength greater than that of said front electrode.
An electrically responsive target for registering projectile contact which comprises sequentially abutting each other a front insulating layer, a front electrode, an intermediate insulating layer, a rear electrode, and a back insulating layer, said front electrode being a metallic foil having a thickness of at least 0.005 inches thick, said intermediate layer being an open cell foam insulator having a thickness of at least 0.10 inches thick, and wherein said rear electrode is a metallic wire screen having a mesh of about 15 to about 50 and having means to electrically connect said target to an electrical circuit.
An electrically responsive target of a laminated construction comprising a front electrode, a rear electrode, and an intermediate insulating layer, said intermediate insulating layer disposed between said electrodes to provide electrical insulation therebetween, said front electrode being and aluminum alloy foil having a thickness of about 0.001 inches to about 0.005 inches, said rear electrode is a galvanized aluminum screen having a mesh of about 15 to 50 mesh, said intermediate insulating layer being an open cell foam layer having a thickness of from about 0.1 to about 0.2 inches, said front electrode having an open cell foam insulating layer abutting its front face, said rear electrode having a back open cell foam insulating layer abutting its rear face, said electrodes having connection means to an electrical circuit and to a source of electrical energy.
