Author : Prajakta Saitwal, Shruti Gondse, Sherlin HS. |
Abstract | Full Text |
Abstract :It is great responsibility that auto business is heading towards new heights of progression and budgetary advancements. In case we discuss about some previous year growth, researches are at advanced level. Now the revolution in technology is “self driven cars” or “Auto-car”. The main objective of this driverless cars or
self driven cars is to take driving decisions without any interference of human being in decision making. The important factors of self driven car is the sensing device to acquire traffic related data, computer system to process the data, and actuator as controlling device |

CHARGES STORED ON THE SURFACE OF THE AIRPLANE USING BUCKYPAPER |
Author : Sureshmohan.M, Sathishkumar.S, Giridharan.D, Senthil Kumar. M |
Abstract | Full Text |
Abstract :Buckypaper is the new composite material for energy efficient transport. It is not an ordinary paper, but thin layers of composite material strengthened with carbon nanofibers to be stronger than steel, and as light as silk. It has amazing flexibility and strength and weight. Since from their discovery, decades ago as buckyball and nanotubes these peculiar molecules have been integrated with composite compounds. Bonding thousands of these ultrathin sheets together has created the ultimate lightweight super strong material for
aircraft skins and automobile panels. It also conducts electricity and disperses surface heat. It is 10 times stronger than the iron and it is half the weight of the current composites. Lightning strike is one of the major problems in today’s aircraft. By using buckypaper, lightning strike can be overcome by distributing the
charges equally over the airplane. In addition, the surface of buckypaper stores charges like a battery. So there will be no need of batteries in aircraft. So that the weight of the aircraft is reduced. Platinum used in the fuel cell is 1/4th the platinum used in buckypaper fuel cell. The nanotubes have atomic bonds which is enough to make them twice as hard as diamond. But the biggest benefit of all, is the cost saving for the traveller. In future, commercial aircrafts can be made of buckypaper and it would be perfectly safe. |

Author : J. Jerold John Britto, A. Vasanthanathan, Dr. P. Nagaraj |
Abstract | Full Text |
Abstract :Recent advances and cost reductions has simulated interest in fiber optical sensing. This techniquehelps to detect the damage in aircraft structure. Nowadays, most of the critical components of aircraftstructure made up of composite structure. CFRP can significantly reduce the weight while increasingstrength and durability. The weight reduction of the structure will increase the fuel efficiency. Thecomposite structure subjected to static and dynamic loading during the running condition. This paper
overviews the cost effective material selection (CFRP) and damage detection setup using fiber opticsensor under dynamic loading condition. The spectrum received from the damage detection setup isanalysed to ensure the size, shape and damage condition. The intensity of spectrum depends on the
damage size of the given component. The entire paper shows the damage detection under dynamic loading with various indenter for impact.

CONCEPTUAL DESIGN OF FOLDABLE ALL-WHEEL DRIVE OFF-ROAD MOTORCYCLE |
Author : S. Saravana Prabhu, Dr. R. Gandhinathan |
Abstract | Full Text |
Abstract :All Terrain Vehicles (ATV) and dirt bikes have wide range of applications apart from motorsports due to their ability to operate easily in rough terrains. But portability of these vehicles is difficult due to their size, which limits their applications. However foldable light weight motorcycles with off road capabilities were found to overcome this limitation. Thus, the work mainly focuses on designing an innovative foldable light
weight motorcycle with all-wheel drive system, so that it can be used for off road transportation. Also Portability limitation of existing vehicles can be eliminated. Initial design requirements for design of foldable all-wheel drive off-road motorcycle are found. Based on that data, four concepts are generated and
concept selection has been carried out using Pugh chart and weighted matrix method. |

COMPARATIVE MECHANICAL TESTING ON HYBRID FIBER REINFORCED POLYMER COMPOSITES |
Author : T. Rajasekaran, S. Vigneshkumar |
Abstract | Full Text |
Abstract :Composite materials consist of two or more constituent materials, the fiber and the matrix. Generally the matrix is of ductile and fiber is of brittle in nature. Fiber reinforced polymer composites are becoming very popular and replacing conventional materials nowadays, because of their excellent properties suitable for various applications. The properties of fiber reinforced polymers are comparable to most conventional
materials like metallic materials. This is due to their lower density compared to the higher density in metals which leads to higher strength to weight ratio for the composites compared to that of the metallic materials. These composites are also easier to obtain in desirable shape and require much less energy in making the required product. There are number of fibers available for making composite material including synthetic as
well as natural fibers. Natural fibers are available in plenty and it is also eco friendly, which go waste if not utilised further. In this experimental work, different fibers sisal fiber, kenaf fiber, banana fiber, carbon fiber and rice husk hybrids are separately used to prepare a specimen using a thermosetting polymer unsaturated polyester and suitable hardener, accelerator and catalyst for the improvement of the process, various mechanical testing such as Tensile test , Flexural test, Impact test of the composite material under various conditions are carried out. The properties of the were compared. ASTM standards were followed for carrying out all these tests.
