Abstract

In the present scenario the growing concern of the people living in every part of society is the ever increasing price of fuel and the harmful effects caused due to higher level of pollutants in the atmosphere. One of the closest solution to control the above two concern is the evolution of the hybrid vehicle. Any vehicle that combines one or more sources of on board power that can directly or indirectly provide propulsion power is a hybrid vehicle. The hybrid vehicle attempts to significantly increasing the mileage and reduce the emission levels of a gasoline powered engine and Diesel Engines. The water hybrid vehicle uses an HHO (Oxy Hydrogen) generator to supply hydrogen on demand by Electrolysis. The Electrolysis process is carried out in HHO Dry Cell, when the current starts flowing through the stainless steel plates electrolysis process is carried out between the 2 terminals of the plate by which water molecules get separated as HHO gas. The integration of this produces great results. The IC Engine of hybrid vehicle during operations simultaneously charges the battery using alternator which run through generator. The water hybrid system is an attempt to provide an affordable low emission fuel efficient vehicle with performance standards better than most of the conventional Engines.

Abstract

Bamboo/Glass fiber reinforced polymer composites are replacing conventional metal alloys owing to their ecofriendly nature. Natural fibers as reinforcement offer number of advantages than traditional synthetic fibers. This paper aims to determine the mechanical properties namely, Tensile strength(TS), Impact strength (IS), Flexural strength (FS) and Hardness of hybrid composites reinforced with Bamboo/Glass fiber. The Treated bamboo fibers are mixed with the glass fiber in the proportion of 1:1, in order to reinforce in epoxy resin with different fiber lengths(5,10,15 mm) and fiber weight fractions of (20%,30%,40%). Experiments are planned according L9 orthogonal array in Taguchi's design of experiments. The control parameters considered were fiber length (Fl) and percentage Fiber weight fraction (Wf). In this work an attempt has been made to model the mechanical properties through response surface methodology (RSM). Analysis of variance (ANOVA) is used to check the validity of the model. The results indicated that the developed quadratic models are suitable for the prediction of mechanical properties of the Bamboo/glass fiber reinforced epoxy composites. The experiment result reveals that tensile strength, flexural strength and hardness were decreased with increase of fiber length but impact strength increased with increase of fiber length.

Abstract

In this work, composite rods of glass fiber/epoxy and carbon fiber/epoxy with 80% of fiber loading and 20% of matrix are produced by using pultrusion technique. Pultrusion is a continuous process for manufacture of composite materials with constant cross-section. Reinforced fibers are pulled through a resin, possibly followed by a separate preforming system, and into a heated die, where the resin undergoes polymerization. Many resin types may be used in pultrusion including polyester, polyurethane, vinylester and epoxy. These two types of rods are subjected to tensile test, chemical absorption and impact tests at various temperatures like room temperature and at below room temperatures.
