Abstract The holy Quran, from more than 1400 years, told us that Zul-karnain had made a metallic composite material between iron and copper [1,2] as follows: “Bring me sheets of iron” — until, when he had leveled [them] between the two mountain walls, he said, “Blow [with bellows],” until when he had made it [like] fire, he said, “Bring me, that I may pour over it molten copper * So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration.”: Translation of verses 96 and 97 in Surah Al-Kahf (18), The holy Quran [3]. According to the above story, the matrix is copper, while reinforcement is iron of this metal matrix composite. The present paper is going to investigate the Metal-Matrix Composite Material (MMC) suggested by Zul-karnain at different manufacturing conditions by using the experimental method. The effect of reinforcement temperature on the integrity of such MMC is one of the main goals of the present work. The mechanical behavior of the present QMMC is also examined in the present research as preliminary study. Furthermore, the finite element method is used to predicate the debonding force of MMC based on Virtual-Crack-Closing-Technique (VCCT).

The composite material is a combination of two or more materials with different physical and chemical properties. The composite has superior characteristics than those individual components. A hybrid composite is the one which contains at least three materials. When the matrix material is a metal, the composite is termed as metal matrix composites (MMC). The MMC is a composite material with two constituent parts, one being a metal. The other material may be another metal, ceramic or fiber. Among all the MMC’s, Aluminium is the most widely used matrix material due to its light weight, high strength and hardness. This paper deals with the fabrication and mechanical investigation of hybrid metal matrix composite Al - SiC. The fabrication is done by stir casting by adding the required quantities of additives into the stirred molten Aluminium. The results show significant effect of mechanical properties such as tensile strength, yield stress and flexural strength. The internal structure of the composite is observed using Scanning electron microscope (SEM) and found that are formation of pores in them.

At present, in order to increase the weight efficiency of parts and structures of promising aircraft and rocket-space vehicles, various types of additive technologies and topological optimization methods are being actively introduced. Their purpose is a significant reduction in time and financial costs in the manufacture and creation of fundamentally new geometric solutions. The article considers approaches to selecting the geometric parameters of the strength elements of the flight vehicle body made of a metal-matrix composite material based on VT6 titanium alloy, reinforced with a finely dispersed silicon carbide powder, which is produced by direct laser growth technology. On the basis of numerical simulation, the dependences of the metal-matrix composite material physicomechanical and thermophysical characteristics on the volume fraction of silicon carbide have been determined. It was found that the use of a metal-matrix composite material and the optimization of geometric parameters with adaptation to the direct laser growth technology allows reducing the weight of the strength element of the flight vehicle body by more than 30% (depending on the overall dimensions).
