Titel
RCF-Tapes for Sustainable High Performance Lightweigt Construction
Abstract
This study addresses the production and the processing of highly aligned tapes from recycled carbon fibers (rCF). Starting from a modified carding process, the rCF are stretched and fixed into semi-finished tape products along subsequent processing steps. The characterization methods used in this study to test the composite include tensile and bending tests, the determination of fiber volume content, and eddy current technology to measure fiber orientation. Composites build on basis of these rCF-tapes reaches a bending strength of approx. 800 MPa in fiber direction and stiffness about 70 GPa at a fiber volume content of around 36 %. Such properties are approximately double those of nonwovens made by comparable state of the art technology routes. By using various fiber placement technologies, those high properties can be used in a load-path-compliant manner.
