Abstract - In recent years advanced polymer material
composites are used in automobile ,marine applications in glass fiber with polymer resin. To enhance the properties of GFRP, in this work, white cement was used as filler material with glass fiber – polymer resin matrix. The composites were fabricated by varying the weight percentage of white cement in matrix material, 0 wt%, 5 wt% and 10 wt% respectively. The composites were fabricated by hand-layup process, As per ASTM standards, the specimen were prepared and studied experimentally for mechanical properties. The results were compared for different percentage of filler material. It was observed that addition of cement lead to change in mechanical properties of GFRP.

1.INTRODUCTION ( Size 11 , cambria font) Fiber reinforced polymer composite materials show strong future for integration into the immense infrastructure. Typically, these materials have protracted and fruitful lives; are light in weight and easy to construct; provide excellent strength to weight characteristics; and can be fabricated for customer specifications, strength, stiffness, geometry, and other properties. The current work is focused on the behavior of randomly arranged E-glass fiber and epoxy LY556 polymer resin composite purely meant for marine application. Randomly arranged GFRP has great application in the marine parts because of its cheaper cost and resistance to water (mainly salt water). Usually these marine parts are constructed using metal or wooden slabs, which are more susceptible for the damages from the water, so as to protect these structures from the adverse effect of water the GFRPs are used as the coating material to the areas of automobile, marine which comes in contact with water . Research is underway worldwide to develop newer composites with varied combinations of fibers and fillers so as to make them useable under different operational conditions. In most of these applications, the properties of polymers are modified using fillers. A notable advance in the polymer industry has been the use of fiber and particulate fillers as reinforcements in polymer matrix. Particulate fillers are of considerable interest, not only from an economic viewpoint, but as modifiers especially the physical © 2017, IRJET

properties of the polymer. It is well documented in the literature that majority fillers have a positive influence on mechanical properties. Particulate fillers consisting of ceramic or metal particles and fiber fillers made of glass are being used these days to dramatically improve the properties of composite materials [1]. Various kinds of polymers and polymer matrix composites reinforced with metal particles have shown the increased tensile strength, impact strength, hardness and flexural strength [2-3]. These engineering composites are desired due to their low density, high corrosion resistance, ease of fabrication and low cost [4-6]. Similarly, ceramic filled polymer composites have been the subject of extensive research in last two decades. The inclusion of inorganic fillers into polymers for commercial applications is primarily aimed at the cost reduction and stiffness improvement [7, 8]. Along with fiber-reinforced composites, the composites made with particulate fillers have been found to perform well in many real operational conditions. When silica particles are added into a polymer matrix to form a composite, they play an important role in improving electrical, mechanical and thermal properties of the composites [9, 10]. Hence by this research survey, it is motivated to make some experiments to investigate the effect of the varied volume fraction of cement as filler content on glass /polymer resin. The objective is to investigate the mechanical properties. 2. Fabrication Method: Fabrication of composite is done by conventional method called hand lay-up method. A mold of dimension 310 × 210 × 3.2 mm is used. Epoxy resin with its corresponding hardener in a ratio of 10:1 is thoroughly mixed. Mold releasing silicon spray is applied to mold releasing sheet and then the chopped fiber, mixed with the resin is gently poured on the sheet which is placed inside the mold. The purpose of releasing agent is to facilitate easy removal of the composite from the mold after curing. The mixture is allow to set inside the mold for a period of 24 hr under a pressure of 20kg over the cast. Then the specimen is cut into appropriate dimension for mechanical tests.
