Carbon nanotubes (CNT) are an outstanding development in the field of nanostructure. Unique characteristics of Carbon Nanotubes (CNT) make them a suitable reinforcing agent in Aluminium (Al) Metal Matrix composites. These composites are being anticipated in aviation for their high explicit quality just as utilitarian materials for their energizing mechanical attributes. Most researches have focused on their strength and stiffness of Al-CNT composites for more than a decade. There is no specific review paper for the mechanism of fatigue failure of CNT-Al composites. Thus the objective of this review paper to addresses the fatigue failure mechanism of Al - CNT composites.

Carbon nanotubes (CNT) are an outstanding development in the field of nanostructure. Unique characteristics of Carbon Nanotubes (CNT) make them a suitable reinforcing agent in Aluminium Metal Matrix composites. These composites are being anticipated in aviation for their high explicit quality just as utilitarian materials for their energizing mechanical and warm attributes. The property of carbon nanotube strengthened aluminum network (Al-CNT) composites mainly depends on the percentage weight of reinforced material in the base material. Thus the main objective of this review paper to addresses the concentration of CNT on tensile strength, yield strength and compressive strength of CNT - Al matrix composites.

The recent development in graphene had a great impact on the physical and chemical properties of any metals or epoxy composites. Our idea is to form a graphene composite that exhibits optimized properties and characters that meet the requirement of the industry field. This paper is a study about properties of graphene when coated with other metals and the application study of graphene with Nanotechnology. Our aim in this project is to fabricate a graphene-based composite that differs the functional and physical properties of the element based on the specific application of radio wave control that protects the human form being affected. Thus, this application can be achieved through coating the graphene on the required element which results in graphene epoxy composite. Various researches were made on this field, yet the application-based survey is still in progress. Thus, we decided to fabricate the epoxy composites based on graphene oxidation.

Technological progress in number of areas to include aerodynamics, microelectronics, sensors, micro-electromechanical systems (MEMS), micromanufacturing, and more, is ushering in the possibility for the affordable development and acquisition of a new class of military systems known as MicroAir Vehicles (MAV). MAVs are a subset of Uninhabited Air Vehicles (UAV) that are up to two orders of magnitude smaller than the manned systems that permeate our contemporary life. Recent advances in miniaturization may make possible vehicles that can carry out important military missions. These missions can be possible if MAVs can fulfill their potential to attain certain attributes to include: low cost, low weight, range, endurance and precision. So the present work concentrates on development of MAV with ornithopter (flapping wing) concept. The development of flapping wing utilizes a combination of two things, biologically inspired design and incorporation of composite material. The MAV has imitate the wing structure as a basic concept of aerodynamics and kinematics. Hence in this paper work, study and analysis of aerodynamics of bird and insect has been carried out. The main objectives of this project are, to create an ornithopter with best available flapping using kinematic arrangement and to attain crash resistance power by building the MAV with carbon fiber composite rod.

For given condition of (temperature and humidity) of suction air, the delivery air condition depends on the system parameters (depth, radius, length and air mass flow rate), thermo physical properties of the surrounding earth (thermal conductivity and specific thermal capacity) and earth surface environment (ambient temperature, ambient humidity and solar irradiance)[1,3].Sensitivity analysis of system performance is essential for understanding the relative importance of different parameters of design of a optimum system [2,5]. For the steady state periodic input air condition and the performance of the system can be measured in terms of heating potential during the winter period and cooling potential during the summer period. Sensitivity of the system performance parameters (heating potential in winter and cooling potential in summer) to the changes in system parameters or thermo physical properties of the surrounding earth has been analysed and the result is present is in this paper

Hastelloy X is a nickel-based superalloy, widely used in high temperature applications such as aircraft and land-based turbines. This technical paper deals with the high temperature erosion mechanisms and the surface roughness of Hastelloy X. The erosion mechanism of the Hastelloy X was studied using hot air jet erosion experiments at 800°C with varying parameters, like angle of impingement and erodent velocity. Characterization of the eroded samples was done using scanning electron microscopy (SEM) micrographs and high-resolution universal tribometer to determine the erosion mechanisms and surface roughness values. SEM micrographs of eroded samples reveal that lip formation, cutting, and ploughing are the dominant erosion mechanisms of Hastelloy X at a 45° angle of impingement, whereas, at 90°, it is lip extrusion followed by flattening of lip and detachment of platelet.

IN718 is a Nickel-based superalloy, widely used in high-temperature applications such as aircraft, and land-based and marine turbines. This technical paper deals with high-temperature erosion behavior and its mechanism of IN718. The erosion mechanism of the IN718 was studied using hot air jet erosion experiments at 800 °C with varying parameters such as angle of impingement and erodent velocity. Characterization of the eroded samples was done using SEM micrographs and high-resolution universal tribometer to determine the erosion mechanisms. SEM micrographs of eroded samples reveal that lip formation, cutting, and ploughing are the dominant erosion mechanisms for IN718 at 45° angle of impingement, while at 90°, it is lip extrusion followed by flattening of lip and detachment of platelet. These mechanisms eventually retard the particle impact velocity, thus enhancing erosion resistance.

Nickel based superalloy, Inconel 718, is one of the main candidates for high temperature applications such as air craft, land base and marine turbines. This technical paper deals with high temperature erosion behaviour and its mechanism of Al2O3–40TiO2 (A40T) coating on Inconel 718 alloy. Al2O3–40TiO2 coatings through plasma spray method were made on Inconel 718. The erosion behaviour of the A40T coating was studied using hot air jet erosion experiments at 800°C with varying parameters like angle of impingement and erodent velocity. Characterisation of the samples was carried out using SEM images, and mechanisms of erosion are discussed. Images (SEM) reveal that the A40T coating exhibit ductile and brittle behaviour by ploughing and network cracking with grain chipping at 45° angle of impingement, while at 90°, it is brittle behaviour by network cracking and grain ejection. This investigation concludes that A40T coating on IN718 provides good erosion resistance at elevated temperatures.
