Imitating nature has inspired the development of self-healing polymers. This research examines how self-healing polymers can aid the design manufacture world by replacing the need for external joining methods, such as mechanical fixings, welding, or adhesives. The self-healing mechanism will be considered for being used as a joining mechanism of multiple parts in an assembly. The research will argue how imitating intrinsic healing in nature inspires the use of poly (urea urethane), which will produce a more innovative method of building prototypes. The significance of being able to build assembly models without fixings and joints would provide better use of materials and less distribution costs. Journals and published papers on the newly developing polymer materials, their biomimetic inspiration and possible suitable additive manufacturing methods shall be examined. The research will discuss the possibility of the further sustainable and economic development. Additional interviews with leaders, in the field of developing materials and additive manufacturing methods, will provide further insight to the proposal. The self-healing polymer will be assessed on which additive manufacturing method would prove to be suitable for the possibilities of printing. The research will gather available information of the developing material to assess the possibilities and show a full understanding of the proposed concept.
In the present work, A356/SiC Metal Matrix Composite (MMC) with different weight percent of SiC particles were fabricated by two different techniques, such as Mechanical stir-casting and Electromagnetic stir casting. The wear and frictional properties of the metal matrix composites were studied by performing dry sliding wear test using a pin-on-disc wear tester for both electromagnetic stir casting samples and mechanical stir casting samples. The wear rate increases with the addition of normal force, while decreases when the percentage of reinforcement is increased. Frictional coefficient increases by increasing the normal force and percentage of reinforcement. By increasing percentage of reinforcement and using electromagnetic stir casting process, the higher frictional coefficient and lower wear rate are obtained.
Abrasion is an important phenomenon to know the mechanical erosion of rocks, which generally occurs due to the different elements that are in constant contact with the surface of the rock. Abrasion leads to decrease in mechanical and aesthetical properties. Typical abrasion testing was performed on three different marbles using varying loads and sliding speeds according to European standard EN 14157. From experiments, it was observed that the abrasion wear generally increased with respect to the applied load. However, it is also observed that Makrana and Andhi marbles showed a linear behaviour than Bhainslana marbles indicating that they are less sensitive to the increasing loads. The abrasion wear of marbles increased linearly with respect to sliding speed initially and then started decreasing with further increase of sliding speed. Further, correlation analysis was done to rank according to abrasive wear of the marbles with respect to load and speed.
In the last two decades, the global need for lightweight, high- performance and cost effective materials have increased from conventional to composite materials because they possess a good combination of properties like low density, high strength, improved physical, thermal, and mechanical properties. Aluminium Metal Matrix Composites (AMMCs) are one of the most interesting engineering material alternatives used in sectors like automobile, defense, aerospace, and many other engineering applications. AMMCs are fabricated through various routes like stir casting, powder metallurgy, diffusion bonding, and infiltration process. Amongst these, stir route of casting is the most simple, economical and flexible type. The uses of agro-industrial waste in AMMCs have been getting more attention as they can reduce the overall cost of the composite and also improves some of the physical and mechanical properties like density, hardness, stiffness, specific strength, thermal stability, creep, and fatigue resistance. This paper describes a comprehensive review of the utilization of agro-industrial wastes like rice husk ash, sugarcane bagasse ash, coconut shell ash, groundnut shell ash, and red mud which serves as the reinforcement in the development of AMMCs.
The fiber - reinforced polymer composites are normally exposable to fatigue behavior, fatigue properties, and fatigue failure. Increasing stress ratios can lead to better fatigue performance in fiber - reinforced polymer composites. The images from SEM (Scanning Electron Microscope) expose that under a high level of stress, the critical fiber breaking failure, which is the dominant damage, occurs along with matrix cracking and interfacial debonding. The experimental indication is supported by microscopic assessment at different stages of the fatigue life and fracture surface investigations. This paper reviews the fatigue behavior and characteristics of fiber - reinforced polymer composites. To predict the fatigue life of fiber - reinforced polymer composites not only the effects of a load, but other experimental input variables, such as maximum stress, fiber orientation, and stress ratio were also considered. The output variables were the number of cycles to failure stress ratios and load frequencies which are also reviewed in this paper.
