Most engineers likely know the new Boeing 787 Dreamliner is made primarily of carbon-fiber-reinforced epoxy composites. Considering that carbon fibers were first developed in late 1960s, this is remarkble progress. Carbon-epoxy composites have outstanding properties so it is not surprising that they have become the baseline materials in aerospace and sporting goods. The fact that composites don't have the production constraints of metal let Boeing engineers optimize 787 aerodynamics. The composite air-frames also weigh less but are stronger than conventional airfrmes, with a commensature impact on operating efficiency and performance. They don't corrode and resist fatigue that eventually makes metal structure weaken and crack.
