Fiber Orientation Prediction for Discontinuous Fiber Composites: Fundamentals and Future Trends

08 Feb 2023 | Online Presentations | Contributor(s): Johnathan Goodsell

When composite materials with discontinuous fibers are processed into their final shape, any flow alters the fiber orientation pattern and affects the properties of the final composite. It is now standard practice to predict fiber orientation patterns and the resulting mechanical properties in...

Fiber-Optic-Based In-Process Monitoring of CFRP Structures for Material Quality Assurance

27 Jan 2022 | Online Presentations | Contributor(s): Johnathan Goodsell
