Advanced Visualization Methods for Porosity in Carbon Fiber Reinforced Polymers

This work presents advanced methods for the characterization and visualization of porosity in carbon fiber reinforced polymers (CFRP). The developed visualization pipeline for the interactive exploration and visual analysis of CFRP specimens enhances the evaluation workflow for non-destructive testing (NDT) practitioners. Besides the calculation of local pore properties, i.e., volume, surface, dimensions and shape factors, we show novel visualization approaches to explore pores in a CFRP specimen. We introduce Porosity Maps (PM), to allow for a fast porosity overview showing areas with high and low porosity in the specimen. Pores are filtered with parallel coordinates according to their local properties. Furthermore a histogram-based best-viewpoint widget is introduced to evaluate and visualize the quality of viewpoints on a sphere. The advantages of our approach are demonstrated on real world CFRP specimens.
