The present work deals with the study of some aluminum (Al) composites reinforced with metallized-graphite (MG) particles prepared by mechanical milling and powder metallurgy routes. Density, morphology evolution and mechanical performance of composites were investigated as a function of MG concentration and milling time. The as-milled powders were characterized by X-ray diffraction and optical/electron microscopy; meanwhile, the mechanical testing was carried out on cylindrical specimens prepared from powders by powder metallurgy. Evidence reveals that high-energy ball milling induce a homogeneous dispersion of graphite nanoparticles in the Al matrix; this is related to an enhancement of hardness and strength response of studied composites. The composite sample with 0.5% MG addition (in weight) reached an increase of 40% on hardness and 50% on strength (compared with pure Al sample); nevertheless an adverse effect was observed with longer milling and/or higher MG concentration.

“…Since a metal catalyst, such as, nickel can be utilized for the growth process of CNTs, nitric acid-containing oxidants are generally refined with CNTs for biological applications, which can regulate the chemical composition of CNT surfaces by making carboxylic acid groups at the terminal CNT end. CNTs are commonly utilized in biomedical applications ( Figure 8) because of their high aspect ratio, low density, and electrical and physical properties [106][107][108][109][110][111]. Zhang et al investigated the interaction between cells and modified multi-walled carbon nanotubes (MWCNTs) for biomedical applications [112].…”

In the field of tissue engineering, conductive hydrogels have been the most effective biomaterials to mimic the biological and electrical properties of tissues in the human body. The main advantages of conductive hydrogel include not only its physical properties, but also its adequate electrical properties, thus providing electrical signals to cells efficiently. However, when introducing a conductive material into a non-conductive hydrogel, a conflicting relationship between the electrical and mechanical properties may develop. This review examines the strengths and weaknesses of the generation of conductive hydrogels using various conductive materials and introduces the use of these conductive hydrogels in tissue engineering applications.

“…Aluminum, magnesium and their alloys are widely used as materials for such a matrix; and particles of aluminum oxide (Al 2 O 3 ), silicon carbide (SiC) and others, as reinforcement [1][2][3][4]. Using multi-walled carbon nanotubes (MWCNT) as the strengthening phase is promising for composite production, since such nanotubes have high mechanical properties (elastic modulus up to 1.5 GPa), which, in turn, affects the mechanical properties of the resulting composite materials [5,6].…”

The mechanical properties measurement of multiwall carbon nanotube reinforced nanocrystalline aluminum matrix composite AIP Conference Proceedings 1661, 080025 (2015) Abstract. It is known that metal matrix composites reinforced with non-metallic inclusions are of great interest in various fields of technology owing to a good combination strength to weight ratio. Carbon nanotubes (CNTs) are expected to be ideal reinforcements for composite materials due to their high modulus and low density. In this paper metal matrix composites were obtained through hot pressing of powder mixtures Al-1% and 5% carbon nanotubes at different isothermal time. Hardness and density of materials went up with an increase in the isothermal holding time. However, the hardness of composites decreases with an increase the nanotubes content in the material.
