    Composite materials are widely used for different applications today. Most of the composites are to affect the environment whereas bio-based composites material are bio-degradable. There are lot of physical parameters such as elongation, moisture, and absorptionetc., compared with the other type of composites.This paper deals with preparation and investigationof bio based composites of natural fibres in epoxy resin. Naturalfibres used here are sisal and coir fibres which are mixed with is epoxy. This composite is manufactured using hand lay-up process. Mechanical properties of each composite are determined through tensile, flexural, impact tests. Key words: Coir, Sisal, epoxy composites

    In an area of increasing pollution and environmental degradation, it has become imperative to manufacture products that do not affect the environment. In the field of composite materials, Natural fiber, such as, luffa possess good reinforcing capability when properly compounded with polymers. The fiber is relatively inexpensive, originate from renewable resources and have high strength as others. Development of a simple manufacturing technique for luffa fiber composites that minimises fiber degradation and can be used in developing countries, is the main objective of our study. This paper deals with preparation and investigation of bio based composites of natural fibre in epoxy resin. Natural fibre used here luffa which are mixed with epoxy resin. This composite is manufactured using compression moulding process. Mechanical properties of each composite with and without treatment are determined through tensile, flexural, impact tests. Keywords—luffa fibres, Compression moulding method

    This paper presents new design of energy recovering system in braking system. In general, regenerative brake is an energy recovery mechanism which slows down a vehicle or object by converting its kinetic energy into other form, which can be either used instantly or stored until needed. This contrast with conventional braking systems, where the excess kinetic energy is renewed to heat by friction in the brake linings and therefore wasted. In our methodology, the too much kinetic energy is converted useful mechanical energy and stored by spring. Keywords: Brake, High pulling power, Regenerative power.

    In this present study,Al-7075,TiC&Ricehuskash(RHA) metalmatrixcomposites(MMCs) were fabricated by stir casting method. Differentweightfractionsofreinforcementwereused to fabricate thecomposites.Theproperties likedensity, hardness,andultimate tensilestrengthwere investigated. The additionof rice husk ash particles reduces thedensityof composite while increasingthe mechanicalproperties. In demand to achieve good compulsory between the matrix and reinforcement particle, 1% of magnesium is added. The hardness of the sample at room temperature was measured by Rockwell hardness test machine. When The volume fraction of TiC and RHA reinforcement increases, the scale of hardness also upsurges. This study summaries that 7075 hybrid composite with high hardness can substitute the conventional material used in automobile components for better performance and longer life. The specimens without any post-weld heat treatment belongingto a different set of parameters tested, exhibited a high joint efficiency (most of them ranging from 90% to98%) with respect to the ultimate tensile strength of the base material Al-7075. Keywords: Al-7075,TiC,Rice husk ash and 3%Mg

    Mechanical engineering is not more involved in robotics since Mechatronics and robotics found a vast application in implementing the concept of running a robot model using servo motors and drives, since large amount of energy is required to run the robot model. The other thing is, it requires more power and initial cost is much higher and implementation of the concept is more difficult as compared to that of the other concepts in mechanical. In order to overcome this, here we are designing the six legged walking robot based on kinematic mechanisms without any controllers. Kinematic robot is the application of Kinematics & Robotics with Chain drive system. The walking system of kinematic robot can be controlled using the chain drive system. With simple mechanisms and a small electric motor, the Kinematic robot can be executed.
