By choosing an appropriate combination of reinforcement and matrix material, manufacturers can produce properties that exactly fit the requirements for a particular structure for a particular purpose. Composite laminates are produced by consolidating alternate layers of precursor wires or fibre mats and metal matrix sheets or foils under temperature and pressure. A monotape (i.e., a unidirectional lamina) in which a fibre mat is sandwiched between two metal sheets or foils, forms the basic building block. Several complex composite components .
