Damping characteristics of carbon nanotube reinforced aluminum composite

Effect of Thermoelastic Behavior on Interfacial Debonding and Particulate Fracture in AA1100/TiN Nanoparticulate Metal Matrix Composites

“…A linear stress-strain relation [14][15][16][17][18] at the macro level can be formulated as follows: σ = Cε (10) where σ is macro stress, and ε represents macro total strain and C and is macro stiffness matrix. For plane strain conditions, the macro stress-macro strain relation [3][4][5][6][7][8][9][10][11][12] is as follows:…”

“…Several reinforcing materials were tested to improve strength and stiffness. Important nanoparticulates are silicon carbide [3][4][5][6], alumina [7][8][9], alumina trihydrate [10], carbon [11,12], silicon nitride [13,15], boron carbide [16], titanium boride [17][18], etc.…”

Review of Journal Bearing Materials and Current Trends

“…Ceramic compounds like SiC, Al2O3, and Carbon nanotubes (CNT) were widely used as reinforcements (Casati & Vedani, 2014). Deng et al, 2007 reinforced 2024Al with multi-walled carbon nanotubes (MWCNTs) and studied their damping behavior under various frequencies and temperatures. Authors observed a significant effect of frequency on the damping capacity of nanocomposite above 230 0 C and improvement in damping capacity even at temperature 400 0 C. Shehata et al, 2009 produced Cu-Al2O3 nanocomposites by mechanochemical methods and evidenced the improvement in properties in terms of density, microhardness, and abrasive wear resistance.…”

Aluminum foil reinforced by carbon nanotubes

“…These methods include the manufacturing of a powder compact followed by its hot deformation [4]. Compacts are produced by spark plasma sintering [4], cold pressing followed by sintering [5], explosive compacting [6], hot isostatic pressing [7] and hot pressing [8]. The final operation of composite manufacturing is hot extrusion [4] or hot rolling [9].…”
