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

Simulated Microstructures

• Fibers Elongated in one direction

Simulated Microstructures

• Diagonal Fibers

Simulated Microstructures

• Random Fibers
