Plastic heat sinks will be getting a huge push on new Boeing aircraft, possibly starting on the Dreamliner. They offer additional opportunities to reduce weight and improve design through net shape injection molding. “This is a coming attraction,” says Dr. Alan G. Miller, director of technology integration on the Dreamliner. “This technology is already in the marketplace, but is just now moving into aircraft. Thermoplastics can become heat sinks through high loadings (30 to 40 percent) of carbon-graphite fiber or ceramics. Suppliers of thermally conductive thermoplastics include LNP Engineering Plastics (GE Plastics), RTP, Cool Plastics, and DuPont On the thermoset side, suppliers include Epoxies, Etc.
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.
