The primary sources of biomass for the lignin feedstock material for the carbon fiber production equipment in a new federal Carbon Fiber Technology Center will be:
Switchgrass grown for production of cellulosic ethanol and related biofuels.
Hybrid poplars (Populus species) similarly grown for production of cellulosic ethanol and related biofuels.
Hard and softwood tree plantations (Tree Farms) grown for pulp and paper production (primarily softwood in North America).
Waste wood materials (sawdust, wood shavings, etc.) from the forest products industry.
That’s according to Dr. Frederick S. Baker, CSci, CChem, FRSC Distinguished R&D Staff at the Oak Ridge National Laboratories (ORNL) in Tennessee. The purpose of the project is to dramatically reduce the cost of carbon fiber so that it becomes affordable for use in automotive composites.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
