Composites

Composites What is a composite Material? A broad definition of composite is: Two or more chemically distinct materials which when combined have improved properties over the individual materials. Composites could be natural or synthetic.

Characteristic Behaviour of Aluminium Metal Matrix Composites A Review

This paper presents a summary of work reported on Aluminium metal matrix composites with different reinforcements. Aluminium metal matrix has growing demand in aircraft, automotive and other industries due to its light weight, high strength to weight ratio, corrosion resistance and workability. The work is done by reviewed of research Papers, Articles, Magazines, references books etc. The present work focus on mechanical properties and surface texture of aluminum matrix composites AMCs reinforced by silicon carbide, fly ash, TiO2, graphene and B4C and with different wt by using stir casting technique. Each reinforced material has an individual property which when added improves the properties of the base alloy. Effect of different reinforcement on AMCs on the microstructure analyses and mechanical properties like tensile strength, hardness, density, electrical resistivity and wear behaviour is also discussed in detail. Major applications of different AMCs are also highlighted in this work.

Study on Behaviour of Hybrid Fibre Reinforced Cementitious Composites

This paper highlights the material properties of the Bendable concrete for the effective development of new structures and maintenance of existing structures. The material researchers have conducted a lot of experiments based on sustainability, durability and safety point of view. As a result of the attempts, finally a new material was established in the last decade. The proper selection of the fibre, mixing of the composite exhibit strain hardening and multiple cracking behaviour of the material. The strain hardening behaviour of the Bendable concrete gives significant advantage under flexural loading. The crack width developed under loading is very small when compared with conventional concrete due to the bridging effect of the fibre. The material properties of Bendable concrete reinforced with following 0.5 , 1.0 , 1.5 , 2 of steel fibre and 0.1 , 0.15 , 0.2 , 0.25 of polypropylene fibre. The optimum strength attained at 1.0 of steel fibre and 0.1 of polypropylene fibre and has been claimed to be the most promising proportion of the fibre content. A series of experiments were carried out to determine the compressive strength, tensile strength and flexural characteristics of Bendable concrete.
