Efficient thermal management in many avionics system is vital because there is a growing need to minimize the weight and volume of the system. Thermal management is a critical and essential component of maintaining high efficiency and reliability of electronic components. Adequate cooling must be provided while meeting the weight and volumetric requirements, especially for passive air-cooling solutions in avionics applications where space and weight are at a premium. With recent advancements in material science and increase in demand for more aggressive cooling solutions, it has become critical to invent, manufacture, characterize, and implement advanced thermal materials for the design of compact and low weight systems. However due to its isotropic properties of the materials, their thermal performance and reliability can be fully understood. Based on physical, mechanical and thermal properties of aluminum 2024 and alumina we incorporate various approaches for finding out the feasibil
