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.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
A fun and informative tour you can attend at the upcoming Design & Manufacturing Minneapolis, MD&M Minneapolis, and other events there, is the Materials Innovation Tour on Wednesday afternoon. I'll be leading it.
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.
