This research investigate the effect of uncoated and coated chopped carbon fibers with alumina Al2O3 or Tri calcium phosphate (TCP) on the impact value of acrylic poly methyl methacrylate (PMMA) denture base resin.
To improve bonding between carbon fibers and coating materials powders, the surface of carbon fibers has been treated with Para amino benzoic acid (C7H7NO2) and poly vinyl alcohol (PVA) was also used.
The morphology of the coating layers has been examined by field emission scanning electron microscope (FE-SEM).
According to the tests results, PMMA reinforced with uncoated chopped carbon fiber presents high impact strength value with bad aesthetic.
Samples prepared by coated carbon fiber with Al2O3 or TCP have high impact strength values when compared to control group with good aesthetic.
The measured value of impact strength shows a noticeable increase accordingly with the increase of PVA and decrease of used fiber.
