There’s a revolution in technology to make planes lighter. Use of composites in the Boeing 787 Dreamliner is well known. Not so well known is a new hexagonal honeycomb core material made of polylactic acid for lightweight panels. The biobased material also has the benefit of a smaller carbon dioxide footprint than oil-based plastics. In the last six months, a Belgian company called EconCore has optimized the production technology to produce PLA-based hexagonal honeycomb cores using a continuous production process. Moments after a core is produced, skin layers are added in a second step of the continuous production process.
Skins could be made from unfilled PLA material to make a mono material panel or, in case a higher performance is required, could be replaced with consolidated flax in a PLA matrix. One potential application is aircraft interiors, which currently use a polypropylene honeycomb material. The new technology was launched at the recent JEC Composites show in Paris.
A new compression molding compound material combines the light weight, strength, and rigidity of carbon fibers with the flexibility and lower cost of glass materials in a composite compatible with automotive production.
Plastic bearings are real and millions of them are in use doing heavy-duty jobs we used to think only metals could do. Some of Germany-based igus's bearings are traveling around the world as functional parts in a car to demonstrate what they can do.
Baxter showed off his 2.0-derived moves at ATX West this year. The big red guy still looks pretty much the same, but has some new abilities, mostly due to software. The research robot version is now being used in corporate R&D departments as a design platform.
End-production using 3D printing, including objects made of multiple materials in one pass, is getting closer to reality as we saw on the exhibit floor at the recent Pacific Design & Manufacturing Show.
