For better understanding glass epoxy composites with 3 different compositions were used (GE, GE+Silica, GE+Alumina+Silica, GE+Silica+ Alumina + Alumina trihydrate). Wear Characteristics were studies for abrading distances of 250, 500, 750, and 1000 m, using 212µm silica sandapplying 20 and 40 N loads.Alumina, silica, and alumina trihydratenano fillers increased the wear resistance. From the result it is evident that abrasive wear rates were reduced as the abrading distances increased. Keywords: Glass epoxy, three-body, abrasive wear, wear volume, specific wear rate I. INTRODUCTION In material science, wear is erosion or sideways displacement of material from its derivative and original position on a solid surface performed by the action of another surface is related to interaction between surfaces and more specifically the removal and deformation of material on a surface as a result of mechanical action of the opposite surface. Fiber reinforced polymer matrix material play an important role in much industrial application because of their good properties such as high tensile and compressive strength, controllable electrical conductivity, low coefficient of thermal expansion and good fatigue resistance. There are five different types of wear, namely abrasive wear; adhesive wear, surface fatigue, fretting wear and erosion wear [1]. Abrasive wear is typically categorized by the contact environment and the type of contact. The contact type defines the abrasive wear mode. In general there are two types of abrasive wearing i.e. two body abrasive wear and three body abrasive wear. Many scientists have studied the abrasive wear behavior of polymer based composite material. Ranganathaet al. [2] investigated three body abrasive wear ofAl 2 O 3 filler on CFRP composites. The materials used in this study are fabricated using hand layup technique. They observed that Abrasive wear loss decreases with increase in the percentage of adding filler alumina to the composites. Ravikumar et al [3] Investigated effect of particulate fillers on mechanical and abrasive wear behavior of polyamide 66/polypropylene nano composites. All particulate-filled PA66/PP composites were prepared using twin screw extrusion followed by injection molding.His results indicate that addition of nanoclay/short carbon fiber in PA66/PP has significant influence on wear under varied abrading distance/loads. Further, it was found that nanoclay filled PA66/PP composites exhibited lower wear rate compared to short carbon fiber filled PA66/PP composites. In addition, the worn surface morphology of the samples was also discussed. Navin Chand et al. [4] studied the Three-body abrasive wear of short glass fiber polyester composite. They observed that the abrasive wear of the composite shows dependence on all the test parameters like applied load, sliding speed and abrasive particle size. The size of the abrasive particle and applied load tends to increase abrasive wear volume of the composites, whereas wear rate tends to decrease with increasing sliding velocity at constant applied load and particles of size ranging 200–300 μm. Harsha, and U.S.Tewari [5] investigated the ‘’Abrasive wear of glass fiber reinforced polysulfone composites. They observed that their wear resistance deterioted because of fiber reinforcement. With an increase in glass fiber percentage, elongation to break is decreased. This is a controlling factor for abrasive wear performance.Gaurav Agarwal et al. [6].investigated parametric optimization of three-body abrasive wear behavior of bidirectional and short kevlarfiber reinforced epoxy composites. They observed that theoretical values of specific wear rate are calculated based on the given wear model and further compared it with experimental specific wear rate values. The error values for bi-directional Kevlar fiber reinforced epoxy composites lies in the range 0-8%, Whereas, for short Kevlar fiber reinforced epoxy composites error lies is in the range of 0-5%.Suresha et al. [7] studied the Three-body abrasive wear behavior of particulate filled glass–vinyl ester composites, observing that abrasive wear volume increases with increase in abrading distance/loads for all the samples.
