Abstract: A structural composite is a material system consisting of two or more phases on a macroscopic scale, whose mechanical performance and properties are designed to be superior to those of constituent materials acting independently. FRP composites are slowly emerging from the realm of advanced materials and are replacing conventional materials in a variety of applications. However, the mechanics of fiber-reinforced composites is complex owing to their anisotropic and heterogeneous characteristics. In this paper, the micromechanical behavior of the square unit cell of a fiber reinforced composite lamina consisting of boron and Silicon Carbide fibers embedded in Alumina matrix, has been studied. A three-dimensional finite element model with governing boundary conditions has been developed from the unit cells of square pattern of the composite to predict the Thermal Gradient and Thermal Flux of A6061-Boron / Silicon Carbide fiber reinforced lamina for various volume Fraction . A finite element model incorporating the necessary boundary conditions is developed and is solved using commercially available FEA package to evaluate the Thermal properties. The variations of the Temperature at the fiber- matrix interface with respect to the Thermal Gradient & Thermal Flux are studied. This may result in the separation of fiber and matrix leading to deboning. This analysis is useful to realize the advantages of A6061-Boron / Silicon Carbide composites in structural applications, and to identify the locations with reasons where the Temperature is critical to damage the interface. The present analysis is useful to identify the composite effect in selecting the materials for reasonable properties.
