Abstract [en]

This report is a Master’s Thesis that was done at swerea SICOMP in Piteå from December 2011 to May 2012. The thesis was done as a part of the larger project Triple-Use, which aim is to increase the manufacturability of high performance polymer composites. More specifically, this thesis covers the automated manufacturing of dry preforms for jet engine guide vanes using stitching.

The work started by doing a literature study to ascertain what is currently state of the art within automated preforming using stitching. The study showed that there are several automated stitching machines especially designed for dry preforming currently available today. A number of concepts of how to produce the guide vane preform were discussed. A stitched preform was manually manufactured according to the concept which was considered as most promising. The preform was stitched together along the leading and trailing edge with good results.

The work has shown that it is possible to automatically produce dry preforms using stitching instead of binders. But further investigation is needed in order to decide which method is most suited for the guide vane preforms.
