Abstract EN
This research has studied the effect of addition glass fibers (woven and chopped) and Zirconium oxide Nano-particles (ZrO2) with different weight percent to the conventional poly (methyl methacrylate) (PMMA).
The prepared Nano-crystalline ZrO2 powder with particle size of about 95nm was syntheses directly by sol-gel method.
The gel dried at 100oC for 1 hour and annelid at 400oC for 3 hours.
The conventional acrylic resin prepared with 2:1 powder to liquid ratio to prepare pure sample, composite samples prepared by reinforcing PMMA with woven or chopped glass fiber (8, 12) wt.%, and reinforcing by (1,2,3) wt.% of prepared ZrO2 Nano-powder.
The structural tests include: (XRD, AFM, and FTIR).
The crystallized phase composition of dried ZrO2 powder after annealing in air at 400oC has been identified by x-ray diffractometry (XRD).
The grain size of dried ZrO2 Nano-particles by atomic force microscope (AFM).
The impact strength (I.S.) was measured by using Charpy impact test.
The mechanical test done in order to compare the impact strength between pure and composite samples.
From the result, the reinforcing PMMA with glass fiber in two forms (woven and chopped) improve the impact strength, while increasing of ZrO2 Nano powder loading led to decrease the impact strength.
