Thermal Characteristics of Composites with an Aluminium Alloy Matrix Reinforced with Silicon Carbide and Graphite
Journal Title: RECENT - Year 2015, Vol 16, Issue 46
Abstract
The aim of the paper is to analyse the thermal stability of hybrid composites (MMCH) with AlSi7Mg03+10%SiCp+3% Graphite, used in the automotive, aeronautic, microelectronic industries, by thermal analysis, type DIL (dilatometric analysis) and TGA (thermogravimetric analysis) correlated with techniques for structural investigation (SEM/EDS). The results obtained, show that the reinforcing elements influencing the thermal expansion phenomenon and the phase transformations. The linear expansion coefficient (CTE), determined utilizing the Kerner model, extended for hybrid composites, is similar to the one determined through experiments, being influenced by the thermal characteristics, the volume fraction of the matrix and the reinforcing elements. A similar influence was recorded in the case of thermogravimetric analysis.
