A Quick Review
• Glass Fibre Reinforced Composites (Polymer: Polypropylene)
• Processing Conditions
• 2 Samples
• Micro-CT Images: DICOM Format
• 3D Visualization and Segmentation
• Fibre Metrics: Length, Orientation, Width etc.

Concerns
• Not enough number of samples for establishing linkage
• No experimental property data
Simulation of Microstructures & Property Data • Generate a large set of simulated microstructures
• Obtain property data using Finite Element method
