Development and Investigation of The Production Process of the Aluminum Matrix Composition Mechanically Alloyed With Single-Walled Carbon Nanotubes and the Composition Material Made of it

Abstract

The effect of a new suggested by authors approach for alloying of the aluminum matrix powder with carbon nanotubes is described in this paper. The manufacturing science is designed for receiving the highly-homogenous in volume dry mixture «aluminum powder – single-walled carbon nanotubes» suitable for synthetic processing of the aluminum matrix composition by the mechanical alloying and for producing of finished aluminum matrix composition materials. The effect of the experimental investigation of production processes of the aluminum matrix composition and workpieces of finished aluminum matrix composition materials is described in this paper.

The Study of the Flat Grinding Process of Workpieces of Composite Materials

“…The alloying process has been carried out in MR. The carbon content in the mixture has been 3, 4 and 5 % by mass [15][16][17].…”

The Study of the Preliminary Forming Process of the Highly-Homogeneous Mixture Consisting of the Aluminum Powder – CNT in the Production Technology of Composite Materials

“…-the matrix powder PAD-1 -97,5 % of the weight; -single-walled carbon nanotubes TUBALL (SCNT) -2 % of the weight; -stearic acid -0,5 % of the weight. The mixture has been normalized and then alloyed in the mechanical reactor of the original design which includes two inside elements vibrators fastened on a single horizontal axis creating of vibration and power impacts on the wall grinding bodies in two mutually perpendicular directions with the phase shift of 30° [9,10].…”

“…In the eyes of many experts the efficient dispersion of CNT in the powder of the aluminum matrix in case of its successful realization during the synthesis of composite granules from composite powders and then of ready composites using of the intensive mechanical deformation including in particular the mechanical alloying method, is a basis for achieving of high physical and mechanical performance capabilities of composites. Authors of these papers truly state that clustering and agglomerating of CNT is a crucial technological issue [9][10][11][12].…”
