Purpose: The aim of this work was optimization of composite matrix solidifcation process with use of thermal properties of components and geometrical characteristics of transition zone related with reinforcing particles morphology. Design/methodology/approach: The method was based on quantitive image analysis. The reinforcing particles morphology was described by morphological modulus. With use of numerical simulation the changes in temperature and its derivatives after time and direction in studied composite micro-region appeared. Findings: As a result of this studies the forecast procedure for composite structure evaluation was obtained and for which optional solidification theory can be used. Analysis of particles morphology influence on matrix solidification process is a proposed novelty. Research limitations/implications: The work enables in enginereeng practice verification of components from technological point of view by thermal and geometrical properties selection and thus by introducing changes to the particle – matrix (casting) – mould – surrounding system. In this stage the procedure does not include the diffusion between matrix and reinforcement related to its relative motion. Evaluation of incomplete wetting and transition zone phases occurance does not permit tribological or fatique properties forecasting. Originality/value: The proposed procedure is useful for composite properties forecasting based on components thermal and geometrical characteristics.
