INNOVATIVE MANUFACTURING, DESIGN AND ASSESSMENT OF ALUMINIUM MATRIX COMPOSITES FOR HIGH TEMPERATURE PERFORMANCE.

Objective


Recent developments in processing technology have enabled the manufacture of aluminium based composite with reinforcements which are stable above 300 C, opening the possibility of major new industrial applications in automotive and aerospace applications. Fundamental materials science problems have been identified for these important candidate materials. One basic weakness is in the understanding of how mechanical performance is determined by the complex interaction between matrix reinforcements and processing routes. The essential objective of this project is to underspin industrial progress through a materials science research consortium focused on the following:
shape, size and volume fraction of reinforcements in the microstructure;
interface reactions for selected reinforcements;
the influence of thermal expansion mismatch within the composite on elevated temperature performance;
the evaluation of microstructural damage and performance parameters for life prediction under monotonic and cyclic load at a range of temperatures and under various environmental conditions.

The object of the research is to optimise manufacturing processes to produce microstructures which exhibit excellent temperature performance in selected aluminium alloy systems and allow predictive engineering design of components for European industry.

The work is on schedule with preliminary studies of the materials selection/manufacturing routes in place. This involves all 5 partners plus selected industries.
