The electrical conductivity of Fiber-Reinforced Polymers (FRPs) may be used to reduce the dangers of lightning strikes, radar radiation, and aerial radio frequency transmitters. Metal Matrix Composites (MMCs) were created to guard against Electromagnetic Interference (EMI) in the aircraft's electric and electrical systems. High-Intensity Radiated Field Protection (HIRFP) aircrafts are required to be manufactured from a metal matrix consisting of Al6061, Al2O3, and Fly Ash (FA) to keep up with the ever-increasing needs of industry. The current work considered three MMC combinations. MMC1 is AL6061+10% and Al2O3+5% FA, MMC2 consists of AL6061+15 and Al2O3+5% FA, and MMC3 of AL6061+20% and Al2O3+5% FA. These MMCs made the shielding more effective at different percentages. The material electrical properties were interpreted based on experiments. Analytical approaches include the testing of the electrical parameters of materials to measure the shielding effectiveness. The calculated shielding efficiencies MMC1-55.7dB, MMC2-57.2dB, and MMC3-59.1dB allow the composites to be employed in aircrafts. This indicates that, for specific applications like HIRFPs, the constructed MMCs perform well.

Nowadays, fly-wire is only used for flying-related things. All plane controls depend on electronics, but they also must deal with high-intensity radiated fields. This equipment might need an electromagnetic shield to protect it from outside electromagnetic pollution. The current work aims to develop a mesh around the operating equipment to protect and make it work better. AL6061 was used to create a shield with a metal matrix composite. Here three combinations of Metal Matrix Composite (MMCs) were considered to protect from the high-intensity radiated fields. These MMCs are AL6061+10%Al_2 O_3+5% FA (MMC-1), AL6061+15% Al_2 O_3+5% FA (MMC-2), and AL6061+20% Al_2 O_3+5% FA (MMC-3) made the process of shielding more effective at different percentages. Explements are Measures that take the electrical characteristics, and they are by Shielding Effectiveness (SE) of different concentrations of fly ash and Al_2 O_3.SE of 50 dB is achieved; hence these MMCs can be used in aircraft and other applications as a shield.

Since composite materials were initially used in airplanes a few decades ago, substantial research has been done on problems such as lightning strike protection (LSP) and electromagnetic interference (EMI) shielding. In the current state of technology, the aerospace industry needs cutting-edge materials to meet requirements like lower weight and higher values of strength and stiffness and protect against electromagnetic interference. On the other hand, the metallic mesh performs poorly at high frequencies (UHF and SHF). Many present and future equipment on airplanes can only operate in the frequency range referred to above. Metal wire mesh matrix composite (MWMMC) materials may be employed to shield airplanes against electromagnetic interference (EMI) as a result of this research. In this work, we made three different MWMMCs represented as MMC-1 with 95% AL6061+5% Fly ash, MMC-2 with 90% AL6061+10% Fly ash, and MMC-3 with 85% AL6061+15% Fly ash. In this article, a stir-casting method was used to try to make Al6061 metal matrix composites that were made stronger with different amounts of fly ash particles. With fly ash, the AL6061 metal matrix composite protects against lightning strikes. So that it may serve as an aircraft surface MWMMC. The material's thickness should be maintained as low as possible. It decided to explore oblique incidence with a different mix of fly ash, reinforced to pure AL6061, to provide more significant shielding to better approximate the signal toward the practical case. Compared to the plane sheet, the shielding effectiveness of the materials and the weight of the material will be reduced. In other words, the maximum shielding effectiveness obtained was 37dB and 20 dB. The shielding effectiveness of 40.5 dB of the manufactured composite is obtained, and it is beneficial for aerospace applications.

One of the significant problems facing aerospace applications over the past two to three decades was fuel consumption. The aircraft industry prefers composite materials (Fiber Reinforced Plastic) to resolve this issue. These composite materials have less weight and good mechanical properties. The major drawback with these fiber-reinforced materials was the inability to conduct the high electrical fields and electrical currents, which cause damage to the aircraft's structure when lightning strikes occurred. The designer should consider a lightning strike protection (LSP) system that allows current and field lines to pass freely through the surface while providing EMI shielding for the aircraft. The best method for allowing the current and field through the aircraft surface by the mesh structure. The mesh structure is examined in this study to offset the decreases in density and fuel consumption. This mesh structure was made using the AL6061 metal matrix material. AL6061 metal matrix composite electrical properties were taken into considerationdepending up on the reinforcement or strengthening of fly ash particulates at different percentages at X-band. The composites shielding effectiveness is gradually increased to 6 dB.

One of the major problems facing by the aircraft was a lightning strike. To overcome this problem, fiber-reinforced materials have been used. The fiber-reinforced materials have less conductivity. These fiber-reinforced materials can’t eliminate the lightning strike effect. For that purpose, the metal matrix composite materials significantly impacted the aircraft’s internal circuits and physical components from the lightning strike effect. To meet industries dynamic and ever-increasing demands, Al6061 metal matrix composite reinforced with fly ash must be utilized to build the aircraft to offer HIRF. The material thickness should be kept low as possible then it can be used to cover the plane’s surface. To prevent lightning strikes, it might be used to protect electronic components from a concentrated high-intensity radiated field, primarily in Aeroplan configuration. The electromagnetic characteristics of composites are measured using the X-band for normal incidence. The electromagnetic reflection properties of AL6061 reinforced with fly ash are studied in this study for mesh structure. Mat lab Software was used to calculate the maximum reflection loss of 33.88dB for 15% fly ash and 85 percent AL6061 at X-band.
