Abstract EN
PMMA (poly-methyl methacrylate) acrylic resin is commonly utilized in the manufacture of denture bases.
however, its mechanical characteristics may be inadequate for this purpose.
the purpose of this research is to look at the mechanical characteristics (flexural strength, flexural modulus, impact strength, fracture toughness) of PMMA composite by adding two kinds of synthetic fibers polypropylene (PP) and polyacrylonitrile (PAN).
numbers of PMMA composite samples were generated at specified weight ratios of (1.5, 3.5, 5.5, and 7.5 wt.
%) in this study.
research results showed that during fibers ratio increased until max.
point (7.5 wt.
%), a decrease in flexural strength value was observed.
notably, PMMA / PAN composite sample has more influence than PMMA / PP composite.
also, a decrease in the flexural modulus during fibers ratio increases until maximum (7.5 wt.
%), flexural modulus for PMMA / PAN composite were higher than the values PMMA / PP composite specimens.
when it came to I.S, it was discovered that when the fiber ratios were raised, the impact strength rose at a ratio (7.5 wt.
%).
finally, the results of fracture toughness showed an improvement for the composite specimen (PMMA / 7.5 wt.
% PAN fiber).
in contrast to (the PMMA / 7.5 wt.
% PP fiber) composite specimen, there was a decrease compared to the neat sample.
