In the present work, the epoxy-based hybrid composites have developed by combining the Sansevieria cylindrica and Glass fibers into epoxy matrix. Tensile strength, compression strength, TGA and DSC properties of hybrid composites without alkali treatments have been studied. Variations of the mechanical and thermal properties have been studied with different combinations of Sansevieria cylindrica and glass fibers as reinforced into epoxy matrix. The aforementioned mechanical properties optimally improved by increasing the natural Sansevieria cylindrica fiber percentage. The observation established good miscibility of epoxy and homogenous dispersion of Sansevieria/Glass fibers in the epoxy matrix.Keywords

In production systems there are situations in which it is not possible to have a single rate of production throughout the production period and the same cost for each individual unit over the decades. Items are produced at different rates and at different sub-periods so as to meet the requirement. The costs incurred changes as the time progresses due to inflation. The price may vary for each unit depending not only on inflation but also various factors as demand, availability, working unit, setup place etc. This paper models a situation by assuming constant rate of demand, varying rates of production and a constant inflation rate. Special cases are also discussed and a case study is done.Keywords

Aluminium alloys are most extensively used Non-ferrous materials in aircraft and automobile industries. Among the aluminium alloys 6000 series are mostly suitable one by virtue its versability is heat treatment and extrusion capabilities. In the present study the influence of various alloying elements in Al 6061 is undertaken keeping in view the mechanical and metallurgical aspects. Experiments are carried by taguchi philosophy of design experiments. L8 orthogonal array is adapted in selection of compositions of alloying elements for casting specimens and testing is carried to study the mechanical and micro structural properties.Keywords

The objective of the current paper is, to investigate the machinability on Al 6061-Mgo metal matrix considering machinability parameters like speed, feed, depth of cut. Aluminum is remarkable for its low density and its ability to resist corrosion through the phenomenon of passivation. It is widely used for high performance applications such as automotive, military, electricity and aerospace industries because of their improved physical and mechanical properties such as light weight, high strength, good corrosion resistance, malleability, etc. Al metal matrix is the material. In the present work aluminium is used as the matrix and several reinforced materials are embedded into the matrix. Al 6061 aluminum alloy is reinforced with 1.0 weight percentage of Magnesium Oxide (MgO) particles through stir casting. In the present work, the influence of alloying elements in Al 6061 alloy have been investigated Casting of specimen having mentioned composition were prepared using stir casting method. Experiments were performed machining parameters like speed, feed, depth of cut during the turning operation with rake angle 15o per various trials, by changing the machinability parameters and calculated for all trials resultant force and frictional force with the help of merchant cycle and identified optimized machinability parameters.Keywords

7XXX series aluminum alloys (Al 7XXX alloys) are widely used in bearing components, such as aircraft frame, spars and stringers, for their high specific strength, high specific stiffness, high toughness, excellent processing, and welding performance. One of the most commonly used aluminium alloy for structural applications is Al7075 alloy due to its attractive comprehensive properties such as low density, high strength, ductility, toughness and resistance to fatigue. Another important alloy in the Al 7XXX series is Al7178. It has exceptional uses in Aviation field, Automobile sector, and Structural industries. In the present research work an attempt is made to prepare a blend of these two alloys and get the optimum composition which yields high strength Al 7(075+178). A medium frequency induction furnace with graphite crucible was used for the melting. Mechanical properties like Tensile strength and Hardness are selected as the output response along with the Microstructural analysis. Taguchi method was adopted for designing experimental composition of the composite which is prepared.
