Analysis of Mechanical Behavior of Glass Fibre/ Al2O3-SiC Reinforced Polymer Composites

Abrasive water jet machining (AWJM) is the non-traditional machining process which is mostly employed for cutting non-conductive materials. The present work concentrates on the AWJ machining study of various compositions (5, 15 and 25%) of blue-fired alumina-reinforced polymer composite. The addition of reinforcement improved mechanical properties which may affect the machining characteristics. The experiment was conducted by varying the experimental process parameters of pressure, abrasive flow rate, and standoff distance. Kerf angle and surface roughness were affecting process parameters which are required to optimize for quality cutting. The results show that the pressure and standoff distance have a direct correlation with the surface roughness and kerf taper angle. Higher pressure and shortest standoff distance show a smooth surface roughness due to no appreciable loss of kinetic energy in cutting wear zone. Similarly, the increase in the reinforcement percentage increases surface roughness and kerf angle. Fiber delamination and grain embedment in the matrix were studied using an optical microscope.

“…The hardness of aluminium alloy (LM-25), aluminium alloy reinforced with 10% SiC andaluminium alloy reinforced with 10% SiC& 5% Graphite were checked and compared. The hardness of the composites were checked by micro Vickers hardness tester with 0.5Kg load applied [8] The hardness of SiC reinforced composite is higher compared to fiber reinforced composite [14]. The less frictional heat generation in the tool manufactured from aluminium composite will result in less hardness value [15].…”

Use of composites is increasing rapidly in automotive and aerospace applications. In the present industrial scenario, synthesis of Metal Matrix composites (MMCs) with superior wear and mechanical properties is of paramount importance. Researchers have conducted various investigations on MMCs with different reinforcement materials. Hardness test, compression test and wear test were conducted on MMCs with various reinforcement contents and unreinforced Aluminium. The results show an increase in hardness value and compression strength of reinforced MMCs when compared to unreinforced aluminium. The wear rate was also reduced with reinforced MMCs but whereas there was an increase in brittleness. It was also determined that at higher loads, the wear rate of composites increases. The surface roughness of the composites developed decreased with increase in the amount of reinforcement, compacting pressure and sintering temperature.

Recently, composite materials have been used in various domains. The reasons for this are low weight and can withstand high strength. New developments of the conventional composites replacing the metal and metal matrix materials in addition to environmental effects are also very minimal. In this, work is undertaken to prepare the fibre reinforced composites and study their mechanical behaviour of combinations. To prepare the fibre reinforced composite (FRP), glass wool (GW) is incorporated into epoxy resin with the varying weight percentage of 0, 30, 40 and 50 by the way of compression moulding method. The composites were assessed on its properties such as tensile strength, flexural strength, impact strength, hardness and density of the composites and have been performed with ASTM standards at room temperature. The fracture regions were studied using scanning electron microscopy (SEM). From the experimental results, high strength was attained at 40 weight % addition of glass wool into epoxy matrix. It is found that the composites have a better strength, which makes this method more convenient and less costly.
