The Boeing 787 Dreamliner has been boom and bust for fastener suppliers. When production of the aircraft first began, a shortage of fasteners slowed the assembly lines. Now, there’s a glut of fasteners in the supply chain. “We probably haven’t seen an order for a fastener on a 787 or a (Airbus) A380 for the better part of two years,” says Bill Christopher, the executive vice president of Alcoa. Distributors bought a large supply of fasteners for the aircraft-essentially on speculation-before the economy nosedived and the 787 encountered design and production problems. It’s now more than three years late but the first delivery is now expected later this year. The A380 also experienced delays. Christopher told analysts in New York last month that he expects normal fastener demand for the aircraft to resume later this year as well. Fasteners are close to a billion dollar business ($868 million in 2010) at Alcoa.
The new composites manufacturing innovation center is intended to be a source of grand challenges for industry, like the kind that got us to the moon under JFK. These aren't the words its new CEO Craig Blue used, but that's the idea and the vision behind the Institute for Advanced Composites Manufacturing Innovation (IACMI).
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
As the 3D printing and overall additive manufacturing ecosystem grows, standards and guidelines from standards bodies and government organizations are increasing. Multiple players with multiple needs are also driving the role of 3DP and AM as enabling technologies for distributed manufacturing.
A growing though not-so-obvious role for 3D printing, 4D printing, and overall additive manufacturing is their use in fabricating new materials and enabling new or improved manufacturing and assembly processes. Individual engineers, OEMs, university labs, and others are reinventing the technology to suit their own needs.
For vehicles to meet the 2025 Corporate Average Fuel Economy (CAFE) standards, three things must happen: customers must look beyond the data sheet and engage materials supplier earlier, and new integrated multi-materials are needed to make step-change improvements.
