Abstract
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 and ensures the capability of working in complex loading conditions. Aluminum based metal matrix composites textile reinforced by carbon fibre (CF 3D/Al-MMC) have been manufactured by high pressure die casting (HPDC). High cooling and solidification rate of HPDC together and the mismatch of thermal expansion coefficients between matrix and reinforcement cause the creation of thermal residual stresses. The assignation of optimal conditions for heat treatment is essential to reduce the internal stresses and obtain most favourable mechanical properties. This paper contains the quality analysis of manufactured composites by Computed 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. Furthermore, the fracture analysis on the interface between reinforcement and matrix has been done to estimate the quality of adhesion.
