Project Description

Insegt Fiber – A powerful tool for understanding fiber-reinforced composites

This tool can accurately measure the individual centre lines of fibers that are densely packed inside a composite. Thanks to Insegt, the method requires minimal input from the user. For its robustness to image quality, the tool is applicable to i) fast scans acquired while in-situ loading a material and ii) complete bundles acquired at lab sources in reduced times.
See our study on fiber reorientation under compression loading of a unidirectional composite, and the possibilities for characterization of fiber and glass composites from static scans. Fiber orientations and diameters are useful in studying the mechanical properties of real composites, as well the effect of the manufacturing process over the designed architectures.
Whether you need a tool for understanding damage mechanisms, or a fast way of characterizing your fiber microstructure, download Insegt Fiber. Give it a try! We are here to help you!
