Compressive failure in complex NCF composite structures

Reference number
Funding from Vinnova SEK 5 770 000
Project duration September 2013 - February 2018
Status Completed

Purpose and goal

In the KOMPRESS project a graduate student has been trained towards a doctoral degree developing deep understanding of the mechanisms governing compressive strength of textile reinforced composites. The mechanisms have been identified and methods to predict the compressive strength, considering internal waviness, have been developed. Work on the structural level remains in this collaborative research campaign to provide the industry with a validated design methodology for aero engine components.

Expected results and effects

The project results will be used in the development of materials, components and manufacturing processes. It has been shown how internal material irregularities affect structural stiffness and strength. Characterization methods have been developed that will be of use in future research and development activities. The generic knowledge obtained in the project will be spread to other sectors through Chalmers and Swerea SICOMP. For GKN Aerospace the results from the Project will lead to more effective design methods.

Planned approach and implementation

The Project has been performed in cooperation between Chalmers, Swerea SICOMP and GKN Aerospace. The Project has identified mechanisms governing compressive strength of composite materials in actual load carrying structures. Development of the theoretical models has mainly been performed at Chalmers. An extensive experimental study was performed where manufacturing and testing was led by SICOMP. The project has been managed by GKN Aerospace, who also has defined the requirements and the manufacturing processes.

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