Study of tow geometry and resin channels of novel 3D fabrics under in-situ compaction 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 change in 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 transverse compaction and changes in tow geometry and inter-tow channels will be recorded. This study will enable us to quantify the fabric tow geometry and resin channels which will further be used to develop geometrical and flow models for textile composites.

Experiment Design

This study will involve the scanning of 3D fabric samples with 35x35 mm size and will require a resolution of 10-15 micron to study the tow geometry features.

Sample & Safety

3D fabric samples made of carbon will be clampled in two clear polycarbonate plates with two thickness gauges on both side of the plates to keep known thickness of samples.
