Boeing is making another significant design change to the Dreamliner to accommodate yet another problem that had not been previously disclosed. Boeing ordered suspension of fuselage production at an Italian subcontractor in June when it became apparent small wrinkles were forming in the composite skin. Spokesperson Lori Gunter tells Design News: “We have designed a fix for the barrels that have already been built-a simple patch that is installed from the outside of the airplane. We are completing a permanent fix to the design that will accommodate the changes in the stringer without needing to install a patch-this basically consists of adding a few layers of composites in key areas of the fuselage.”
As reported in Design News, Boeing engineers are also redesigning the area where the wing mounts to the fuselage. The Dreamliner is already two years behind schedule.
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.
