- Research on the fabrication of the metal matrix composite reinforced with nanostructured carbon materials (Gr, NDC) and evaluate the applicability of manufactured composite materials in the fields of aerospace, electricity and electronics.
- Contribute to PhD training and promote international cooperation between VAST and RAS.

- The obtained research results confirm that the sintering by isostatic hot pressing technique has improved the mechanical properties of Cu and Al composites reinforced with Gr and NDC materials.
- The Gr/Cu composite materials were fabricated with powder samples prepared by two different methods. In which, the powder sample made by chemical method has the ability to uniformly disperse Gr and improved mechanical properties compared with the high-energy grinding method. Where.
+ Powder samples made by grinding method, after agglomeration, the material hardness increased to 29% and with powder samples made by chemical method, the hardness increased to 40%.
+ Tensile strength of composite with powder samples fabricated by chemical method also showed a significant improvement compared with high energy grinding method. Tensile strength of composites with powder samples made by high-energy grinding method, tensile strength increased by 57%, while for samples fabricated by chemical methods, tensile strength increased up to 82%.
- Gr/Al composite materials have been successfully researched and developed by HIP technique. The Gr/Al powder samples prepared by high-energy grinding have uniform MWCNT dispersion with content up to 2%. Experimental results show that, when the Gr component is added, the mechanical properties of the material increase significantly. The hardness of composite samples containing 2% Gr increased by 48% while the tensile strength increased by 90% compared with Al fabricated under the same conditions.
- Contributing to training 01 PhD student on the fabrication of titanium and titanium alloys by powder metallurgy applied in orthopedic trauma.
- Contributing to promoting international cooperation between VAST and RAS research institutes.

- Determining the sintering technique is HIP and related technological conditions to fabricate Gr composite reinforced with metal matrix composites (Cu, Al).
- Gr/metal composite materials have been researched and developed. Initial results have shown the potential of Gr-reinforced materials in improving the mechanical properties of composites. Explain the variation in relative density, stiffness and tensile strength of composite materials..
