Uneven distribution of fibres in stitched NCF composites

KU Leuven University

1 or 2 semesters

Project description

This research work focuses on the generation of an experimental database on the characterisation of the fibre placement in structurally stitched non-crimp fabric (NCF) composites, to be used for validation of models of their internal structure and mechanical behaviour. In NCF's, several fibrous plies are placed in a pile and then stitched together using a thin polyester thread. For a practical use, several NCF layers are usually stitched together with a thicker thread, which improves the fracture toughness, shear, and out-of plane strength. However, the stitching may compromise processability and in-plane mechanical performance. One of these disadvantages is the uneven fibre distribution inside the fibrous plies, which will be studied in the proposed works on images of cross-sections of stitched composites. The results of the MSc thesis will eventually be implemented in the new version of WiseTex textile modelling software. This is a topic for a hard-working student, as processing of the images requires a lot of manual, minute work. The reward is getting intimate with an important class of materials with wide range of applications. If the student is interested, s/he can take part in development of the models of the materials.

The project is available in the Fall and Spring semester.

Duration of research project: 6-12 months.

Number of places availabl: 1 per semester.

Pre requisites

  • This is a topic for a hard-working student, as processing of the images requires a lot of manual, minute work.
