abstract Carbon fibre (CF) reinforced aluminium (Al) composites show a high potential for lightweight design of structural components subjected to thermo-mechanical loadings. The relatively high stiffness and strength of the metal matrix allow the introduction of extremely high forces, thereby enabling a much better exploitation of the existing lightweight construction potential of this material in comparison to other composite materials. The manufacture of CF/Al-composites by the help of an advanced differential gas pressure infiltration (GPI) technique was developed at ILK, TU Dresden. Specimens made of carbon fibre reinforced aluminium metal matrix composites (CF/Al-MMC) were manufactured by GPI technology using moulds of graphite, nickel coated carbon fibres and different types of aluminium matrices. Examinations such as tensile tests, microscopic analysis and inspections of fracture surfaces provide a relation between mechanical properties of the manufactured CF/Al-MMC and the formation of their microstructure during the gas pressure infiltration process subjected to the type of aluminium matrix.
