OK,
Composite materials are multiple discrete materials that are joined together, and, together, have different properties than the constituents alone. In this case, the aluminum is the matrix, and boron is the reinforcement. That means that it is mostly aluminum metal (I don't know if it is an alloy or pure) with very many, very fine elemental boron fibers embeded within it. The presence of the fibers makes the material much stronger (in certain ways) than aluminum alone.
