Composite to metal joining for guide vanes

Reference number
Coordinator RISE SICOMP AB - Swerea SICOMP AB, Mölndal
Funding from Vinnova SEK 2 000 000
Project duration February 2017 - February 2019
Status Completed

Purpose and goal

The aim of the project was to develop a cheaper RTM-based concept to replace today´s more expensive prepreg solution in the manufacturing of guide vanes. The project has developed a concept and demonstrated its technical and economic potential. Initial calculations indicate that the concept is about 15% cheaper than today´s prepreg solution. The purpose and objectives of the project have thus been achieved.

Expected effects and result

Since the concept´s technical and economic potential is demonstrated, there is the possibility for participating companies to invest further in this technology. GKN shall carry out an internal TLR review that will form the basis for if and how they will invest further in the technology for manufacturing of guide vanes. Future projects and further development are needed, but much of project results and the knowledge that has been built up will be valuable for other areas and not only for manufacturing of guide vanes.

Planned approach and implementation

The project´s setup and implementation have worked well and resulted in achieved goals. Manufacture of titanium brackets was made with additive manufacturing, which is still a method that is under development. This meant that there was some spread on the measurements and these tolerance deviations meant that the design of RTM tools became more complicated. As a result, the project was extended by two months.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
