Abstract

In the current research the SCRATCH behavior of poly methyl methacrylate (PMMA) and its NANOCOMPOSITEs has been investigated. For this purpose PMMA matrix NANOCOMPOSITEs reinforced with different weight percent of nano sized ALUMINA (0, 5, 10 and 15) were fabricated using compression molding technique. The SCRATCH test was followed the ASTM G171 standard and the test was done using SCRATCH apparatus at room temperature, 5 mm/s SCRATCH rate and different load (10 and 15N). To clarify the SCRATCH mechanism of PMMA and its NANOCOMPOSITEs, microscopic evaluation was performed using scaning electron microscope (SEM). The results show that the SCRATCH hardness of the fabricated NANOCOMPOSITEs depends on the ALUMINA content. While nanoparticles increase from 0 to 15 weigth percent the width of SCRATCH, changes from 274 to 210 µm. Also the results of microscopic evolutions showed that the dominant mechanism in the SCRATCHed pure PMMA is mar damage. Beside, an increase in weigth percent of nano particles up to 5% causes a change in the SCRATCH mechanism from mar damage to craze.An increase in weigth percent of ALUMINA content improves the SCRATCH resistant and eliminates the effects of SCRATCH pattern gradually.
