Rising demands for energy efficiency in the fields of mobility and mechanical engineering have a large influence in the nowadays development of metal matrix composites (MMC). Utilization of fibre and textile reinforcement in the MMC field gives high freedom of designability of reinforcement structure and ensures the capability of working in demanding complex lading conditions. The aluminium based metal matrix composites reinforced by carbon fibre 3D-textile (CF-3D/Al-MMC) have been manufactured by high pressure die casting (HPDC). High cooling and solidification rate of HPDC together with mismatch of thermal expansion coefficients between matrix and reinforcement cause the creation of thermal residual stresses and highly hamper the application of this material. The assignation of optimal conditions for heat treatment is essential to reduce the internal stresses and obtain the most favourable mechanical properties of this composite. Therefore, the effort to investigate an optimal temperature and time of heat treatment has been taken. This paper contains the quality analysis of manufactured composites by Computer Tomography (CT) and scanning electron microscope (SEM) equipped with EDX module and the experimental examination of CF-3D/Al-MMC by the three point bending test. The fracture analysis on the interface between reinforcement and matrix to estimate the quality of adhesion has been done as well.
