  • Effect of Tensile Load on the Mechanical Properties of Alsic
    EKPU: EFFECT OF TENSILE LOAD ON THE MECHANICAL PROPERTIES OF AlSiC COMPOSITE MATERIALS 301 Effect of Tensile Load on the Mechanical Properties of AlSiC Composite Materials using ANSYS Design Modeller Mathias Ekpu* Department of Mechanical Engineering, Delta State University, Abraka, Oleh Campus, Nigeria. ABSTRACT: Aluminium Silicon Carbide (AlSiC) composite materials are used in the electronics industries and other manufacturing companies hence, manufacturing of AlSiC composite materials with the right properties for different applications are vital to most industries. The challenge of testing the same specimens for different properties remains, because most of the tests carried out are destructive. Hence, the use of ANSYS finite element simulation software for the design and analysis of a flat bar specimen. Loads between 3 kN to 21 kN were applied on the specimen since it is within the operating limit of a Universal Tensile Testing Machine (UTTM), while both ends are fixed. The AlSiC composite materials used in this study have a composition of 63 vol% Al (356.2) and 37 vol% SiC and, the results showed that stress was directly proportional to strain. While the calculated Young’s modulus from the stress versus strain plot was approximately 167 GPa for the different tensile loads applied. In addition, the total deformation of the AlSiC composite material increased as the load was increased. Also, the highest deformation of the material was observed around the centre of the test specimen. This is synonymous with the failure observed in practical testing of specimens.

FacultyofEnggandtech., ParulUniversityofBaroda, Abstract: Now, a day’s friction stir welding process has many advantages compared to tradinational welding process. The present work aims assign to prospect to weld two work pieces of aluminum alloy 6061 and aluminum silicon carbide composite and study the effect of mechanical properties of welding joints. In this experimental work welding will be carried out by using different welding speed and tool rotation speed. The Hardness, tensile strength and mechanical properties will be carried out by using different mechanical test. Introduction: Friction stir welding invented by Wayne Thomas at TWI( The Welding institute) Ltd in 1991.It overcomes many of the problem associated with convention joining techniques. Friction stir welding is solid state joining process that uses a non-consumable tool to join two facing work pieces without melting the work pieces material. Heat is generated by friction between the rotating tool and work piece material, which leads to a soften region near the tool. This heat is without reaching melting point and allows traversing of the tool along the weld line. The plasticized material is transferred the front edge of the tool to back edge of the tool of the tool probe and it’s forged by the intimate contact of the tool shoulder and pin profile There are important welding parameters are: 1. Tool design: The design of the tool is critical factor as good tool can improve both the quality of the weld and the maximum possible welding speed.

The manufacture process including wick structure design, AlSiC plate processing and plating, soldering the subparts, and finally filling and sealing is presented in this paper. Considering satellite launch conditions, vibration tests involving low/high level sine sweep, medium/low level random and full random are carried out. The temperature profiles over the entire heat pipe are measured by means of infrared (IR) scanning to study the thermal resistance, heat transfer capacity and heat pipe performance degradation, if any. Both horizontal and vertical orientations with different heating-cooling modes are employed in the performance tests. AlSiC based flat thin heat pipes are proven to have excellent performance characteristics. After 42 weeks life test, thermal resistance in the range from 0.15 K/W to 0.5 K/W has been measured at thermal loads from 20 W to 140 W. The lowest thermal resistance is achieved by testing the performance vertically in the top-cooling and bottom-heating mode.

  • Beryllium Composites for Advanced Avionics Systems Howard Berkowitz, Lockheed Martin Electronics & Missile Systems Tom Parsonage, Materion Beryllium & Composites
    Use of Aluminum-Beryllium Composites for Advanced Avionics Systems Howard Berkowitz, Lockheed Martin Electronics & Missile Systems Tom Parsonage, Materion Beryllium & Composites ABSTRACT Avionics requirements for aircraft and satellite systems continue to increase, requiring higher packaging densities, lower delta junction temperatures, higher heat loads, smaller and lighter packaging utilizing chip on board, BGA and surface mount technologies that continue to challenge materials development. To address these increased performance needs, Materion Beryllium & Composites has developed a family of new metal matrix materials, AlBeMet® and E-Materials, for these increased performance avionics systems. This paper will describe the general material attributes of AlBeMet and E- Materials first, and then look at the application of these properties in the design and packaging of advanced avionics electronic products. These materials offer the design engineer a combination of light weight, high thermal conductivity, and tailorable coefficient of thermal expansion (CTE), high specific stiffness and thermal stability, with mechanical properties that have a high degree of isotropy. These materials are manufactured by conventional powder metallurgy technology, while at the same time being able to be fabricated with conventional aluminum technology. Keywords: Metal Matrix Composites, Aluminum-Beryllium, AlBeMet, E-Materials, Avionics Systems INTRODUCTION AlBeMet® is a family of metal matrix composite made up principally of beryllium and aluminum. We can vary the ratio of the two metals to alter the physical, thermal and mechanical properties. The first composition offered to the market is AlBeMet® 162, a 62% Beryllium/38% Aluminum composite. This material is a powder metallurgy product produced by gas atomization, and the final product forms, rod, bar, tube, sheet are derived by consolidating the aluminum/beryllium powder by Hot Isostatic Pressing (HIP) and Cold Isostatic Pressing (CIP) followed by extrusion or sheet rolling processes.

Engg, National Institute of Engineering, Mysore, India2 Asst. Professor, Department of Mech. Engg. Maharaja Institute of Technology, Mysore, India3 Professor, Department of Mechanical Engineering, SJB Institute of Technology, Bangalore,India4 Abstract: Metal matrix composite (MMC) is an advanced engineering material possessing numerous favourable characteristics like light weight, high strength, high stiffness , ability to be operated at elevated temperatures etc. However, it is very difficult to machine these materials as they contain very hard abrasive ceramic as a dispersed phase in a ductile material matrix phase. Our study aims at casting of AlSiC composite rods with 25% w/w SiC as a composition. The study employs CNC turning operation and Taguchi's L8 orthogonal array is used for experimental design. An attempt is made to optimise the effects of the three parameters viz. Cutting Velocity, Feed Rate and Depth of Cut on the Surface Roughness values (Ra and Rz). Analysis of Variance (ANOVA) has been performed to know the effects of these three factors on the responses using statistical software MINTAB 16. Keywords: Machining, Cutting Parameters, Anova, Statistical Analysis I. INTRODUCTION Metal matrix composites are widely used composite materials in aerospace, automobile, electronics and medical industries. This is because of their superior mechanical properties like strength to weight ratio and high thermal conductivity.
