The effect of silicon carbide (SiC) particle strengthening on polymethyl methacrylate (PMMA)-toughened glass-epoxy composite has been studied. The primary aim of this research is two different tasks. Studying the effect of PMMA toughening on glass-epoxy composite and the effect of SiC particle addition are the two tasks. The PMMA and SiC particles are dispersed with epoxy resin at room temperature and composites are prepared using hand layup method. The composites were subjected for post cured at 80^οC for better performance. The tensile and flexural results showed that the addition of PMMA and SiC improved the tensile, flexural strength and modulus. Similarly, the TGA of PMMA toughened glass-epoxy composite shows higher mass loss whereas; SiC addition retains the temperature stability. The specific wear rate and coefficient of friction (COF) showed that the composites inbuilt with SiC content offered lower sp. wear rate and COF of 0.024 and 0.5. The scanning electron microscopy (SEM) micrographs explicated more shear cups and striations, which indicates improved toughness of composites.

研究了碳化硅（SiC）颗粒增强对聚甲基丙烯酸甲酯（PMMA）增韧的玻璃-环氧树脂复合材料的影响。这项研究的主要目的是两个不同的任务。研究PMMA增韧对玻璃环氧树脂复合材料的影响和SiC颗粒添加的影响是两个任务。在室温下将PMMA和SiC颗粒用环氧树脂分散，并使用手工铺层法制备复合材料。复合材料在80 ^o进行后固化C以获得更好的性能。拉伸和弯曲结果表明，添加PMMA和SiC可以改善拉伸，弯曲强度和模量。同样，PMMA钢化玻璃-环氧复合材料的TGA显示出更高的质量损失，而 SiC的添加保持了温度稳定性。比磨损率和摩擦系数（COF）表明，内含SiC的复合材料的sp。较低。磨损率和COF分别为0.024和0.5。扫描电子显微镜（SEM）显微照片显示出更多的剪切杯和条纹，表明复合材料的韧性得到了改善。
