Imparting Robustness to Out-of-Autoclave Prepregs

09 Mar 2023 | Contributor(s): STEVEN NUTT

Autoclaves have long been used to ensure robustness in the production of composite parts. However, they present a production bottleneck, as well as high capital and recurring costs. Out-of-autoclave prepregs were introduced to allow oven curing and thereby address some of these issues. These OoA...

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

08 Feb 2023 | Online Presentations | Contributor(s): Charles Tucker

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...

Master Laminates to Simplify Design, Manufacturing, and Testing of Composites

12 Dec 2022 | Online Presentations | Contributor(s): Stephen W Tsai

Composite materials and structures have traditionally been viewed as more complicated than metals. With master stiffness and failure envelopes composites are as simple as metals. Stiffness of laminates can be split into two part: one for trace that represents the total stiffness capacity; one for...

Adaptive Multi-Scale & Multi-Fidelity Progressive Failure Analysis of Composites

14 Nov 2022 | Online Presentations | Contributor(s): Tong-Earn (TE) Tay

Although high-fidelity modeling of progressive damage has advanced our understanding of failure mechanisms in fibre-reinforced composites, such techniques are currently still too computationally intensive for direct application to composite structures. The multi-scale nature of damage in...
