Study of tow geometry and shear angle of novel 3D fabrics under in-situ shear loadings

Scientific Case

Textile composites undergo different deformation modes during forming including transverse compaction, in plane shear and tension and out of plane bending. All these deformation modes change the tow geometry of textile preforms leading to a significant change in fibre volume fraction and mechanical properties of the resulting polymer composites. To understand the mechanics of composites and to make simulation tools, accurate knowledge of these tow geometrical changes is needed. In the present work, different novel textile architectures will be studied under in plane shear loadings and changes in tow geometry and shear angles will be recorded.

Experiment Design

This study will involve scanning of fabrics samples of size 40x40 mm by clamping the fabric samples under in-situ shear loadings by a polycarbonate rig. A resolution of 10-15 micron will be needed to study the tow features.

Sample & Safety

The samples consists of 3D glass and carbon fabrics which will be scanned by clamping the fabric samples by a polycarbonate rig specially designed for this testing which can be easily mounted in the Nikon system.
