Development of Fiber Microstructure for Processing of Discontinuous FRCs
Discontinuous fiber-reinforced composites (FRCs) offer a unique advantage: the ability to produce complex-shaped parts through automated, high-volume processes like injection molding, compression molding, and extrusion. But as these composites flow and deform during processing, so does their fiber microstructure—directly impacting final part performance.
In this lecture, Prof. Tim A. Osswald of the Polymer Engineering Center at UW-Madison explores how processing affects:
- Fiber orientation
- Fiber length distribution
- Fiber dispersion and agglomeration
- Local fiber density
The seminar introduces techniques for microstructural measurement in finished parts, and showcases advanced prediction models developed at UW-Madison to simulate how fiber microstructure evolves during processing.
These tools are essential for improving:
Structural performance
Process optimization
Material efficiency
Whether you’re designing high-performance components or scaling up production of fiber-filled thermoplastics or thermosets, understanding and controlling microstructure is key to unlocking the full potential of discontinuous FRCs.
