Characterization of textile reinforcements using image correlation techniques

KU Leuven

1 or 2 semesters

The aim is to study the mechanical behaviour and internal structure of woven textile reinforcements under biaxial tensile and shear deformation using the digital image correlation technique.

Project description

The aim is to study the mechanical behaviour and internal structure of woven textile reinforcements under biaxial tensile and shear deformation using the digital image correlation technique. A thermoplastic textile preform undergoes large shear and small tensile deformations during composite processing into a 3D part. These deformations vary from point to point, changing the local geometrical and mechanical properties of the composite part. Moreover, composite processing is a non-isothermal process, influencing matrix behaviour as function of temperature. Knowledge of the strain distribution is vital for quality assessment of the deformability tests and for understanding of the reinforcement behaviour in forming. Strain mapping system LIMESS of Department MTM will be used to study behaviour of reinforcements during shear and biaxial tension at various temperatures and shear rates. The data will be used to validate predictions of a software package WiseTex.

The project is available in the Fall and Spring semester.

Duration of research project: 6-12 months.

Number of places available: 1 per semester.
