**Abstract Scope** |
The analysis of any composite requires information about the amount of reinforcement present. A common way to determine the amount of reinforcement is to dissolve the matrix and then weigh the remaining reinforcement. The first requirement for this analysis is that the solution used to dissolve the matrix in inert to the reinforcement. For aluminum matrix composites containing aluminum oxide as the reinforcement, this is not possible with common reagents. The common solutions for dissolving aluminum alloys contain Hydrofluoric acid, which dissolves aluminum oxide. Another way to determine the amount of reinforcement is the measure the elastic modulus of the composite and then calculate the amount of reinforcement that leads to that modulus. This paper discusses a method for measuring the elastic modulus for particle reinforced aluminum composites. The method for calculation of the elastic modulus for particle reinforced aluminum will also be discussed. Data will be presented. |
