Snapshot: Forest Service scientists worked with the University of Wisconsin to spin nanocellulose gels into continuous fibers so that they can be used more efficiently in advanced composites. The researchers are optimizing the spinning process and investigating key attributes affecting performance.
Summary:

Most fibrous reinforcements, such as carbon and glass, for advanced composites are produced as continuous fibers or yarns, fabrics, and preforms. These options allow for broad flexibility in design and manufacturing approaches. But nanocellulose preparation methods commonly lead to aqueous solutions and gels, forms that are very different from those used in most advanced composite fabrication methods. Recently, Forest Service scientists worked with the University of Wisconsin to spin nanocellulose gels into continuous fibers so that they can be used more efficiently in advanced composites. The researchers are optimizing the spinning process and investigating key attributes affecting performance such as the alignment of the nanocellulose within the filaments. Other materials (such as polymers) are added to the nanocellulose gel to improve spinning and the performance of the final fiber. Once optimized, the researchers will assess the potential of these nanocellulose filaments, compare them with other continuous reinforcements, and identify applications where they might be used based on the findings.
