“…The demand for functional materials with less weight, more flexibility, more electromechanical coupling coefficient, more yield strength under static or dynamic conditions, better thermal and mechanical durability [1][2][3][4][5][6] compelled the contemporary industries to rely upon the designing of functional composites. Hence, it is prudent to say that there is a desperate need for homogenization and prediction of effective electromechanical properties of functional composites.…”

Representative volume element based finite element method is employed to evaluate all the effective properties of electrostrictive composite. The attention is paid to designing the periodic boundary conditions to be applied to representative volume elements of electrostrictive study. The present study is conducted on particulate and fiber electrostrictive composites, in which electrostrictive ceramic (Pb(Mg1/3Nb2/3)O3-PbTO3- BaTiO3, PMN-PT-BT) is embedded into a nonelectrostrictive polymer (epoxy) matrix. In particulate composite, the spherical particles are randomly distributed and in fiber composites, cylindrical fibers are arranged in a square and hexagonal pattern. The study reveals that the electrostrictive composite does not only depends on the inclusion’s volume but also on their microstructure. The electrostrictive coefficient of the proposed composite is more than its constituent materials owing to the auxiliary flexibility of polymer matrix.

“…[4][5][6] Then, the C f /Mg composites have become an alternative material for the aluminium-magnesium alloy due to the need for lightweight materials. 7,8 Over the last several decades, there has been a considerable increment in the use of C f /Mg composites. A P100/AZ91C composite rigid pipe was prepared by vacuum casting and used in the frame structure.…”

Carbon fibre reinforced magnesium matrix (C f /Mg) composite components were made by liquidsolid extrusion process following vacuum infiltration technique. The effect of varying fabrication parameters (extrusion temperature, infiltration pressure and filling pressure) on the forming quality of C f /Mg components was investigated. The experimental results showed that the extrusion temperature and the infiltration pressure played important roles, and the filling pressure played a secondary role. The components can be obtained at an extrusion temperature of 5908C, an infiltration pressure of 20 MPa and a filling pressure of 0.2 MPa. The ultimate tensile strength of the C f /Mg composite components was 290 MPa, which was increased by 81% compared with that of casting AZ91D.

“…Carbon fibre reinforced magnesium alloy matrix composites (Cf/Mg) exhibit high specific strength and specific stiffness, low thermal expansion coefficient, which produces a good application prospect in aerospace and automobile field [1][2][3]. Cf/Mg composites can be used as a type of lightweight structural materials to replace the traditional aluminium alloy and magnesium alloy, such as satellite antennas, space mounting plates and optical reflector brackets [4][5][6][7] However, the applications of Cf/Mg composites are restrained due to the existence of some microscopic defects, which are caused by inappropriate fabrication parameters.…”

Carbon fibre reinforced magnesium alloy matrix composites were fabricated by using liquidsolid extrusion directly following vacuum infiltration technique. The experimental results showed that the microstructures of Cf/Mg composites depended on the holding pressure. The porosity was reduced gradually, and the densification was improved obviously, respectively, with the increase of the holding pressure. The densification, hardness and Ultimate tensile strength of Cf/Mg composites were significantly improved as the holding pressure increased in the range of 0.1-15 MPa. The densification was not obvious, but the UTS of the Cf/Mg composites decreased gradually as the holding pressure increased in the range of 25-45 MPa.The Cf/Mg composites presented a good performance when the holding pressure was about 15 MPa.
