The key to Boeing’s novel design is “a suite of new technologies” that are being put together for the first time. The most exciting of these technologies is the composite material. Composites are heterogeneous materials that express properties of its constituent materials. By combining different materials, the physical properties of the materials can be customized for different applications. For example, polymer-matrix composites, the type of composite used in the Dreamliner, are used in a wide variety of applications including for military aircrafts, helicopter rotor blades, tennis rackets, and circuit boards.1 The main polymer-matrix material used in the 787 Dreamliner is an epoxy matrix that integrates carbon fibers.
