  3. 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...

  11. 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...

  12. 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...
