Aluminium hybrid composites are a new generation of metal matrix composites that have the potentials of satisfying the recent demands of advanced engineering applications. These demands are met due to improved mechanical properties, amenability to conventional processing technique and possibility of reducing production cost of aluminium hybrid composites. The performance of these materials is mostly dependent on selecting the right combination of reinforcing materials since some of the processing parameters are associated with the reinforcing particulates. A few combinations of reinforcing particulates have been conceptualized in the design of aluminium hybrid composites. This paper attempts to review the different combination of reinforcing materials used in the processing of hybrid aluminium matrix composites and how it affects the mechanical, corrosion and wear performance of the materials. The major techniques for fabricating these materials are briefly discussed and research areas for further improvement on aluminium hybrid composites are suggested.

Aluminium matrix hybrid composites: a review of reinforcement philosophies; mechanical, corrosion and tribological characteristics

Friction stir welding/processing (FSW/P) involving temperature, mechanics, metallurgy and interaction, is a complex solid state joining and processing technology. FSW has been widely applied to join aluminum alloy, titanium alloy and other materials which are difficult to weld by fusion welding. The last scientific study states that FSW has potential to join thermoplastic polymers and polymer matrix composites. In this review, current understanding and development about FSW of thermoplastic polymers and polymer matrix composites, multifunctional composites fabrication as well as dissimilar FSW of metal and polymer are reviewed. Future scientific research and engineering development related to FSW/P of thermoplastic polymers and polymer matrix composites are identified.

A Review of Recent Progress in Solid State Fabrication of Composites and Functionally Graded Systems Via Friction Stir Processing

Friction stir processing has been employed to produce metal matrix composites by incorporating reinforcement particles in an Al 5059 matrix. The fabrication method involved repeated friction stir passes on a groove which contained powder reinforcements, with different processing parameters and tool geometries used for each pass. Various particles with sizes from 130 nm to 4.3 μm, and different process parameters were examined to obtain a uniform distribution of particles within the stir zone. Mechanical properties (i.e. tensile and microhardness) of the Al 5059 matrix MMCs reinforced with Al2O3, SiC, and B4C with particle sizes of 130, 250, and 35 nm respectively were compared. Tensile tests showed 11%, 20%, and 38% increases in yield strength compared to the matrix alloy for composites containing nano-scale Al2O3, SiC, and B4C, respectively. When 4.3 μm Al2O3 particles were employed, higher volume fractions could be achieved which resulted in a 32% increase in yield strength compared to the base metal. The average microhardness value within the stir zone increased from 85 HV in the base material to a maximum of 170 HV in the B4C-reinforced composite. Nano-scale particles seem to be more effective to increase hardness by increasing the particle fraction in the produced composites.
