Lou, recyclable and recycled composites and plastics are a subject that's getting more attention all the time. We covered it here: http://www.designnews.com/author.asp?section_id=1392&doc_id=271489 Since recycled polymers are already being used in heavy truck parts, bridges, and Ford's car seats, among many other uses, it's clear that they must meet the same performance standards as any other plastics. Making materials recyclable is also being investigated. Recycling composites, though, especially carbon fiber-reinforced ones, is a lot more difficult. One of the biggest problems in recycling plastics is when they're made of multiple materials, as composites are. The companies mentioned in the story at the link I gave are pioneers. Some are also working on making carbon composites recyclable.
Ann, I was just talking to my son this morning about cars made from carbon fiber composites and comparing them to cars made from aluminium. Since steel and aluminium are easily recyclable, it makes sense to use them when appropriate. On the other hand, if more composite materials are used I think that there should be standards for recyclability. This material seems to be a good first step.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
So if you can't attend live, attend at your convenience.
