The Investigating to Physical and Mechanical properties of Nano Polyester matrix composites reinforced with Fiber Glass and silicon carbide

An experimental study was conducted to determine the abrasive wear behavior of different weight percentage fiberglass and silicon carbide powder filled polyester composites. The effect of glass fiber and SiC powder concentration and sliding distance on the weight loss of composites has been analyzed. The weight loss depends on fiber glass and powders concentration. The weight loss decreases with the increase of sliding distance and wear resistance increases with the decrease of percentage of weight loss. Strength characteristics on the material depending on the type and quantity of fillers have been tested. Sample having 1 weight percentage (wt%) of fiber glass and 3 percentage (wt%) of SiC show the maximum strength. Density of the Nano composites tends to decrease with adding filler into matrix, While porosity percentage and water absorption percentage of the Nano composites tend to increase. At least morphologies and microstructures of samples were characterized by various techniques such as X-Raydiffraction (XRD), Scanning electron microscopy (SEM), nevertheless the X-Ray diffraction could not identify the phases because of the small percentage of reinforcements.
