A study on Mechanical properties of Vinylester based bio composite with Starch as filler material

In composites a conglomeration produces material properties which are unavailable from individual constituent materials. The use of petroleum based products as constituents in polymer matrix composite has raised concerns regarding environmental issue and non -renewability of the resource. Therefore in this work an attempt has been made to develop a biocomposite material using untreated dupion silk fiber as reinforcement material and vinyl ester as matrix material with Potato Starch used as filler material by hand layup technique.The biocomposites were prepared in varying percentage of filler addition (0%, 10%, 20%, and 30%) and different mechanical tests (tensile, flexure and hardness) were conducted on the samples prepared to the ASTM standards.From the results of the experiments conducted on the specimen it can be concluded that the performance of 10% Starch filler content Biocomposite is satisfactory in all aspects compared to 0%, 20%, and 30% Starch filler content Biocomposites

Investigation of Mechanical properties on Vinylester based bio composite with Gelatin as randomly distributed filler material)

In the present work an attempt has been made to develop Bio-composite Material using raw dupion silk fiber reinforced vinylester matrix in addition with gelatin as filler material with varying percentage using hand lay-up method. The experiments namely tensile, flexural and hardness test were conducted on the standard samples prepared. An appreciable improvement was found in the mechanical properties of the Bio-composite, which can be used for variety of applications in the human bone replacement. The biocomposites were prepared in varying percentage of filler addition (0%, 10%, 20%, and 30%) and different mechanical tests (tensile, flexure and ardness) were conducted on the samples prepared as per ASTM standards. According to literature survey the human femur bone with tensile strength for female is 30.08±7.96MPa. In this work it was found that tensile strength of 30% gelatin filled with Dupion silk fiber reinforced vinylester bio-composite material is 26.86 MPa

Avoiding Drunken Driving Road Accidents by using Alcoholic Sensors

The purpose of this work is to avoid drunken driving accident by using alcohol detecting sensor. The uncontrolled many accidents were happened because of influence of alcohol during driving. To avoid such accidents, we have proposed alcoholic sensor in the vehicle ignition system. This system is integrating the alcohol sensor with microcontroller, relay switch and battery. The alcohol sensor used in this project is MQ-3 which detects the presence of alcohol content in human breath. Vehicle ignition system gets power from battery through relay switch. The ignition system will operate based on the level of Blood Alcohol Content (BAC) in human breath detected by the alcohol sensor and the signal will send to microcontroller, which will supply power to spark plug

Computational Analysis of Heat Transfer through Fins with Different Types of Notches

The Engine is one of the important component in an automobile which is subjected to high temperature and thermal stresses. In order to cool the engine the fins are another component which are used to dissipate the heat from the Engine. Fins are generally used to increase the heat transfer rate from the system to the surroundings. By doing computational flow analysis on the engine cooling fins, it is helpful to know about the heat dissipation rate and the Principle implemented in this project is to increase the heat transfer rate, so in this analysis, the fins are modified by putting different types of notches and are of same material. The knowledge of efficiency and effectiveness of the fins are necessary for proper designing of fins. The main objective of our analysis is to determine the flow of heat at various notches available and the analysis is done by using ANSYS – CFD Fluent software
