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.
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
The US Congress has extended an important tax credit for solar energy, a move that’s good news for future investments in this type of alternative energy and for many stakeholders in the solar industry.
