Ballistics Tests of Fibrous Concrete Dome and Plate Specimens
Abstract
Fibrous concrete plate and inflation-formed dome specimens were fabricated in the laboratory and tested to evaluate their resistance to ballistics. Variables in the investigation included: weapon system (small arms, mortars, grenades, and explosives); range (0 to 200 yds); fiber volume content (0 to 3 percent); thickness (1 to 8 in.); type of fiber reinforcement (mild steel, drawn steel, and fiberglass); and angle of incidence (o to 75 degrees). Test results indicated the following: (1) the inflation-formed domes provide adequate protection from mortars and grenades detonated at ranges of 5 ft or more; (2) the specimens reinforced with fiber are far superior to those without fibers; (3) material systems of the thickness considered do not provide effective protection against demolition charges such as Composition C4; (4) resistance to penetration increases with decreased angles of impact and increased range; and (5) the specimens reinforced with the more ductile steel fibers perform slightly better than those with glass fibers.
