Characterization of Aluminium Oxide (FP) Fibre Reinforced Al-2,5LI-Composites

Metal matrix composites based on Al2O3-fibre reinforcements are gaining increasing attention for structural application. However, the data base concerning its mechanical properties and microstructural characterization remains limited. For the present study an A12O3-fibre (FP-fibre from Dupont) reinforced Al-2,5 Li composite has been investigated. Continuous fibre reinforcements, unidirectional in the 0° and 90°-direction were used for the investigation. Processing of the material was performed by vacuum melt infiltration at LCS, Bordeaux.
