Mortar bars reinforced by chopped steel wire and fiber glass were impregnated with methylmethacrylate which was then polymerized with benzoyl peroxide at 75°F. Monomer loading was 10 wt%, fibrous reinforcement 2 vol%. Tensile, compressive, and flexural strengths were measured for control specimens (without reinforcement and impregnation), reinforced specimens, impregnated specimens, and impregnated and reinforced specimens. Flexural strength was increased significantly by polymer impregnation (510% of control) and by fiber reinforcement (450% of control); the greatest increase was obtained with both polymer and steel fibers (2820% of control). This increase is probably caused by enhanced fiber‐paste bonding with polymer impregnation.
