the flexural properties of poly(methyl methacrylate) (pmma) reinforced with carbon/graphite (c/g) fibers with three different surface treatments were investigated by transverse bend testing after dry and wet storage. the coating agents of commercial unidirectional and braided c/g fibers as well as impurities on c/g fibers for medical uses were characterized by means of high-performance liquid chromatography (hplc). the agar overlay technique was used to assess the cytotoxicity of leachable elements from different fibers and processed composites. composites with both unidirectional and braided tubular c/g fibers were investigated after storage in water fracture stress and flexural modulus decreased when commercial fibers were used as reinforcing material. composites with cleaned and sized fibers gave only minor differences in flexural properties after dry and wet storage.
