Imparting Robustness to Out-of-Autoclave Prepregs

09 Mar 2023 | Online Presentations | Contributor(s): Johnathan Goodsell

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...

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

12 Dec 2022 | Online Presentations | Contributor(s): Johnathan Goodsell

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...
