Analysis of the thermodynamic characteristics of particle reinforced multifarious compositions

The mechanical characteristics of particle-reinforced multifarious compositions are virtually hinged on the characteristics of matrix materials, particles, and the characteristics of the interface between particles. The composite material can be used to improve the disadvantages of a single raw material and expand the scope of application. Multifarious compositions have the advantages, such as high specific strength, high fatigue resistance, and high specific stiffness. For this reason, it is widely and specifically used in aviation manufacturing, aerospace technology, and transportation. Composite materials, titanium alloy, aluminum alloy, and alloy steel have become the main structural materials for aircraft body manufacturing, which is conducive to the improvement of fuel efficiency, simplifying system installation, and shortening assembly time. This research introduces a three-phase theoretical model to analyze the thermodynamic characteristics of particle-reinforced multifarious compositions. The effects of particle volume fraction, particle shape, and interface layer thickness on particle thermodynamic characteristics are analyzed and described.
