Engineers still need to make tradeoffs when trying to achieve improved thermal conductivity in plastics. One of the biggest challenges in plastics design today is efficient heat removal from smaller components, some of which operate at higher voltages. Example: LED arrays are becoming more popular in auto headlamps to conserve energy. Research data presented by DuPont at its pre-K 2007 press conference in Prague show three different approaches: 1) Use of high filler content including carbon fiber achieves a high rate of thermal conductivity but is difficult to mold, 2) Boron nitride coated graphite coupled with copper particles coated with glass also work well, but are not cost effective and also have molding issues, and 3) Use of ceramic particles as fillers does not achieve the level of thermal conductivity required by emerging applications.
Why would the biggest connector company in the world design and build the first fully functional 3D-printed motorcycle? To show TE Connectivity's engineers what the technology can really do in making working load-bearing production parts, and free up their thinking when approaching design problems.
In his keynote address at the RAPID 2015 conference last week, Made In Space CTO Jason Dunn gave an update on how far his company and co-development partner NASA have come in their quest to bring 3D printing to the space station -- and beyond.
A composite based on a high-performance PEEK-like resin we told you about two years ago when it was still in R&D has now been licensed by the US Naval Research Laboratory (NRL) for commercial manufacturing.
