Frictional behavior of dry fiber sheets manufactured by a direct fiber placement process
To evaluate the forming behavior of discontinuous dry carbon fiber sheets made by a novel fiber placement process, friction experiments with fiber materials are carried out. In some cases the non-crimped and not stitched unidirectional fiber material is combined with a reactive powder binder. Testing is done on a setup which was built and evaluated especially for this application. In the experiments the coefficient of friction varies between 0.25 and 1.7. It is shown that the binder material, the fiber angle and the temperature have major influences on the frictional behavior.

The Journal of Plastics Technology is a peer reviewed internet periodical published under the auspices of the Scientific Alliance of Polymer Technology (WAK)
International Polymer Processing, the journal of the Polymer Processing Society, is a discussion forum for the world-wide community of engineers and scientists in the field of polymer processing.
The journal covers research and industrial application in the very specific areas of designing polymer products, processes, processing machinery and equipment.
The Journal of Plastics Technology is indexed in SCOPUS, the largest abstract and citation database of peer-reviewed literature.
