Weight reduction by employing lighter alloys, composites or higher strength materials of smaller cross in novel multi-material designs section are increasingly the key to success, particularly for aircraft, automotive and locomotive structures where energy efficiency is essential to minimise operating costs. In recent years, tremendous progress has been made in the technology of lightweight materials, both metals and composites. However, some products require to combine both groups of these materials with as negligible as possible decrease of achieved synergic properties. Therefore, the development of suitable joining method of different composites is indispensable. For manufacturing of metal matrix composites and lightweight alloys specimens the advanced Gas Pressure Infiltration method has been used. The metal/CFRP multi structural composite has been prototyped by adapted Resin Transfer Moulding (RTM) method. This paper presents an experimental study of the novel joints of dissimilar materials such carbon fiber reinforced polymers (CFRP), lightweight metal alloys and metal matrix composites (MMC) manufactured by the help of adequate methods. The research has been focused on developing of advantageous joining of dissimilar advanced lightweight materials. A specific objective of this paper was to evaluate quality and durability of joints between CFRP and metal alloy/MMC. There are reasonable presumptions that durability of investigated joints strongly depends on arrangement of used materials and types of used components.
