In the present work, analysis of wear behavior, tensile and thermal properties have been done for two sets Poly Methyl Methacrylate samples which is reinforced through licorice particles and pomegranate peels particles. Wear rate resistance is evaluated based on Taguchi’s experimental design L9 (MINITAB 18) under the three factors: weight fraction of fillers (1%, 2%, 3%, 4% and 5% wt.) sliding time (5, 8 and 11 min) and load applied (10, 15and 20N) using a pin-on-disk device. Results display that the samples (Poly Methyl Methacrylate +5% licorice particles and 5% pomegranate peels particles) show the best resistance wear of (0.045×10-6 and 0.10×10-6) respectively. Signal to noise (S/N) results showed that 5% weight fraction (licorice particles and pomegranate particles with PMMA), 11 minutes (sliding time) and 15N (applied load) give the best resistance wear. Statistical analysis of tensile and thermal tests, exhibit that the best mean value of the tensile strength, modulus of elasticity, thermal conductivity, and thermal diffusivity are (±73 MPa, ±70 MPa, ±4.800 GPa, ±4.300 GPa, ±.5600 W/m k, ±.5400 W/m k, ±.3800 mm2/sec, ±.2800 mm2/sec) respectively, of the samples (PMMA+5% licorice particles and 5% pomegranate peel particles). While that the best mean value of the elongation at break (±3.600%, ±3.500%) respectively, of the samples (PMMA + 1% licorice particles and 1% pomegranate peel particles). The results showed that the addition of licorice and pomegranate particles to poly methyl methacrylate resin has improved the properties of wear, tensile and thermal properties.
