The idealization of this research work is to extend the utilization of the naturally available fibers as a key ingredient in the development of a non-asbestos free brake pad. The fibers used in this work are Caryota urens, which is found all over the Asian regions and abundantly available. The compression molding machine was used to develop the non-asbestos free brake pad. The fibers were added in weight percentages of 5, 10 and 15. The various physical, chemical, and mechanical properties were evaluated. Chase test rig was used to evaluate the tribological properties. The combination of Caryota urens fiber with the barytes had a more significant influence on the tribological properties. The brake pad composites with ten weight percent of Caryota urens fibers based brake pads possessed a good coefficient of friction values with less fade values and less fluctuations. Increasing the weight percentage of Caryota urens fibers in the brake pad formulation had a decreasing trend in the wear performance but increased recovery properties.

The usages of composite materials in industries are become as a growing trend due to their inherent material properties such as good strength, low thermal expansion and high strength-to-weight ratio. Among the many classifications of composite materials, natural fiber composites are generally preferred due to their unique characteristics such as bio-degradable property towards the environment. In this study, based on the above selection criteria, from Borassus Tree trunk, Palmyra palm fiber and tamarind powder is selected for the study to use the same for practical application. During this course of examination, tamarind seed powder along with the exact proportionate of Palmyra palm fiber (treated and untreated) has been taken as the reinforcement, similarly epoxy resin has been chosen as the matrix material. To thoroughly validate the physical strength of the individual combination, five set of specimens were fabricated (treated and untreated) as well as their physical strengths such as tensile, flexural, impact and moisture absorption tests were evaluated. Out of all the tests, treated fibers wer shown the better upsurge in tensile, flexural, impact and moisture tests as against the untreated fibers.

Recent developments in (AM) additive developed normally Three-dimensional (3D) printing is a term used to describe printing that is three-dimensional in nature, have enabled researchers to use traditional production methods to create previously unthinkable, complex shapes. Usage of smart materials by the way of adopting the external stimuli in printing is part of a 3D-printing research division called 4D-printing.4D-printing allows for the development of dynamically controllable shapes on-demand by the addition of sometime as another dimension. The potential of 4D-printing has been significantly expanded by recent advances intelligent synthetic materials, new printers, processes of deformation and mathematical modelling. This paper deals with improvement in the area of 4D-printing, with a importance on its practical applications. With explications of their morphing mechanisms, Smart materials are discussed and produced using 4D-printing. Moreover, case study on soft robotics is discussed. We end with 4D Printing problems and future opportunities.

Over the years, transmission system plays a vital role in automobile industry in order to improve the performance of vehicle. Since 323 BC to till date gears plays a vital role in building the integral parts of washing machines, gear pumps, gear motors and wrist watches and so on. The lot of gear applications are extended in all sector of transmission mediums, without gear elements most of the transmission become invaluable in modern engineering industry. This paper aims to design and analysis of gear testing kit, for testing the load generation developed on the gear tooth through brake drum. The main objective of this work is to design the components in a gear testing kit and the components involved in the gear testing domain, are modelled using CATIA software. The main components in our paper are 1/2hp motor, coupling; shaft and bearing, mating gears are made of same dimensions and of different materials. Further the work is to analyse the mating gears which are made of same material and analysis are carried through ANSYS software. Static Structural Analysis is carried through ANSYS analytical Software. Two types of plots are performed and their corresponding Von – Misses stress and Total Deformation at three different torque levels are evaluated.
