Abstract
A novel self-reinforced poly(methyl methacrylate) (SRC-PMMA) consisting of PMMA fibers embedded in a PMMA matrix was developed for orthopedic or dental applications. Three different weaves of SRC-PMMA were tested for bending and fracture toughness. The materials were tested after physiological conditioning and gamma irradiation followed by immersion. It was found that gamma irradiation significantly lowered the bending strength and modulus of the samples, but not the fracture toughness. Loose weave samples had higher porosity after fabrication, and this led to increased water absorption. More porous SRC-PMMA absorbed 2.6% more water than bone cement or optimally processed SRC-PMMA.
