Range of tests conducted on fibrous plaster wad specimens, with eight specimens manufactured in the laboratory for each of the six sample groups. Sample group coding key: B = beta plaster, H = hessian scrim, A = alpha plaster, Q = quadaxial fabric, W = wire present, NW = no wire present, AG = RE Aramid Gel™ sprayed onto specimens
