TL;DR: In this paper, an endeavour has been made to synthesize Al7075 aluminium alloy with reinforcement of B4C and MoS2 as lubricant under various weight percentages of 4, 8% and 12% using stir casting process.
Abstract: The utilization of particulate reinforced aluminium hybrid metal matrix composites is being increased in automotive applications due to its distinct properties. In the present study, an endeavour has been made to synthesize Al7075 aluminium alloy with reinforcement of B4C and MoS2 as lubricant under various weight percentages of 4%, 8% and 12% using stir casting process. The compressive strength, tensile strength, hardness, micro structural analysis and tribological behavior of the synthesized hybrid composites have been analyzed and investigated. From the experimental investigation, it has been observed that the reinforcement particles are uniformly distributed in the matrix alloy as fine dendrites in alumnium solid solutions. The tensile strength, compressive strength, and hardness of the reinforced composites could be increased by adding the reinforcement compared to monolithic alloy. The significant improvement of wear resistance and coefficient of friction of aluminium hybrid composites has been achieved owing to inclusion of solid lubricant (MoS2) along with hard ceramic reinforcement particles (B4C) in the matrix alloy.

TL;DR: In this article, an attempt has been made to synthesis Al6061/SiC/WC hybrid aluminium composites using stir casting method under various mass percentage of reinforcement and the mechanical properties such as compressive strength, tensile strength, hardness and wear resistance have been characterized and investigated.
Abstract: In the present study, an attempt has been made to synthesis Al6061/SiC/WC hybrid aluminium composites using stir casting method under various mass percentage of reinforcement. The mechanical properties such as compressive strength, tensile strength, hardness and wear resistance have been characterized and investigated. From the micro structural analysis of hybrid composites, it has been observed that reinforcement particles have been uniformly distributed without clustering of particles in matrix alloy. The precipitate of Mg2Si and un-dissolved Al6 (Fe, Mn) in aluminium solid solution has been observed as interfacial reaction. The hardness of hybrid composites has been increased due to incorporation of stiffer and stronger reinforcement in the matrix material. The presence of SiC and WC reinforcement in the matrix alloy can significantly enhance the compressive, tensile strength and wear resistance of aluminum hybrid composite.

TL;DR: In this paper, a review describes the characteristics, and potential uses of some natural fibers in order to improve their sustainability and economic values, which is important to determine the optimal intended uses for instance as high quality bio-composite raw material.
Abstract: Understanding the basic properties of natural fibers is important to determine the optimal intended uses for instance as high-quality bio-composite raw material. This review describes the characteristics, and potential uses of some natural fibers in order to improve their sustainability and economic values. The natural fibers have low density and high strength to weight ratio and reduction make them potential as light weight composite and reinforcement materials. The microstructure and chemical compositions of fibers affect the mechanical properties with the fiber cross-sectional area is the most variable influencing the fiber strength. Natural fibers are easy to absorb water due to the presence of hemicellulose that give hydrophilic properties make them less compatible in the interaction with matrix with hydrophobicity properties. Higher cellulose content and crystallinity tend to result better strength properties of fiber while lignin is since versa. Besides that, fiber anatomical characteristics vary between different and same species that affect on the density and mechanical properties. The other factors namely environmental conditions, method of transportation, storage time and conditions, and fiber extraction affect the size and quality of the natural fibers.
