Abstract:

This report results from a contract tasking Computing Center of Academy of Sciences as follows The description of the mechanical characteristics and prediction of the behavior of composite materials reinforced by short carbon fibers and fillers is the goal of the project. The development of the theoretical techniques of the research of reinforced composite materials with taking into account of interphasic interactions between carbon fibers and the matrix represents the task of the project. The experimental validation of the theoretical research by using the measured mechanical properties of reinforced composite materials is also the task of the project. The accomplishment of such tasks has been possible thanks to the recent program of mathematical description and modeling of interfacial interactions and also to the appropriate experimental test. To describe the effective medium characteristics with nanoscale structures the homogenization problem is solved. The methods of solutions of the identification problems are developed within framework of the Project for designed models with nanoscale structures. A strong impact on the knowledge of composite theoretical behavior is expected as a result of this Project. The obtained experimental results should support the extension of the mathematical description to other kinds of composites, mainly fiberepoxy, carboncarbon etc.
