Increasingly novel materials applications are emerging to provide lightweight thermal management functions in aircraft (such as the Boeing Dreamliner) and oher applications. One example is a metal matrix composite developed by a company called CPS Technologies in Norton, MA. In a typical component, a silicon carbide structure is formed in a plunger-type, low-pressure injection molding machine that uses a carrier feedstock that freezes near zero C. The carrier is removed by a phase management sublimation in which the carrier never becomes a liquid. The product can then either be sintered or infiltrated with material such as aluminum.
CPS says that AlSiC produces hermetic packaging that is much lighter than CuMo and CuW, yet has similar thermal conductivity and expansion coefficient. It also costs less.
Dow Chemical and several other companies have launched a program in Omaha, Neb. to divert about 36 tons of plastics from landfills in its first phase, and convert it into energy used for cement production.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
