The International Journal of Mechanical and Production Engineering, vol. 5, pp. 29-25 of 2017, published a scientific research for two academic staff in the Department of Materials Engineering / University of Technology (Dr. Sura S.Ahmed, Ruaa H. Abdulraheem, Eng. Hiba Anwar Abdullah) entitled: (Mechanical properties of composite materials reinforced with ceramic particles)
The polycyclic methyl methacrylate resin material was prepared by hand lay-up molding. Mechanical properties of hardness, tensile properties (maximum tensile strength, elongation at fracture), shock (shock resistance, fracture strength) and shear stress were examined.
For mechanical properties, the composite material (Acrylic + 7% ZrO2) has the maximum hardness of Shore D (72.4), the maximum strength was obtained from (Acrylic + 7% ZrO2) is 33.75MPa, while the elongation at fracture decreases with the increase in filler concentration and less value was (Acrylic + 7% ZrO2) compared to other composites. The shock resistance was higher than (83 J / m2) of (Acrylic + 3% ZrO2) compared with other composites. The fracture strength of the layers increased with the increase of zirconia particles and the highest value was 2.998 MPa/m. Bending resistance and shear stress increased for composite materials with the increasing of Zirconium oxide at 7wt% (81 Mpa) and (1.8 Mpa) respectively.
