Production is scheduled to begin next year on Boeing's 787 Dreamliner, the company's newest passenger aircraft. The 787 is a radical departure in commercial aircraft design in that 50% of it will be manufactured of advanced composites, specifically epoxy and carbon fiber. This is a far greater proportion than in any other civilian airliner. Boeing and its subcontractors have fine-tuned manufacturing and assembly techniques to make the production of large composite structures cost-effective for a mass market. This benefit, combined with the performance and safety of the material, could make the 787 a breakthrough application that pushes demand for advanced composites deeper into the mainstream of commercial products.
