Aluminium composites

Figure 13 SIMS plot of Na, Sn, Mg, and A1 concentrations as a function of time in graphite aluminium composite prepared by the sodium process. (Analysis starts in graphite fiber and proceeds into the aluminium matrix.) (From Ref. 75.)...

The decrease in response is probably due to the poorer material quality (as measured by X-ray diffraction) associated with increasing the aluminium composition. As in the GaN detectors, long time responses (1 ms) are reported for AlGaN devices.

By use of this functionally gradient coating the carbon-fibre-reinforced aluminium composites (C/Al) exhibit excellent mechanical properties. The ultimate tensile strength reaches 1250 MPa when the fibre volume fraction is 35%.

Compared with aluminium, composites have the capacity to deliver significant weight saving, largely because of improved specific stiffness. For example. Figure 4.1... 

Vinod et al used aluminium particles having a specific gravity of 2.7 and a particle size of 127-300 nm to prepare NR-aluminium composites. Nasher et al prepared NR composites incorporating different ratios of Fe with average particle size varying between 26 and 45 nm and Ni particles with an average particle size of between 22 nm and 50 nm.
