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.
