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.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
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.
