Control of Reaction Fronts for Rapid Energy-Efficient Manufacturing of Multifunctional Polymers and Composites

04 Jun 2021 | Contributor(s): Johnathan Goodsell

This lecture describes a new manufacturing platform technology that allows for near net-zero energy fabrication of structural polymers and composites. The approach is predicated on the exploitation of a self-propagating polymerization reaction occurring in a system undergoing reaction and...

Defect Coupling Predicting the Strength and Life of Fiberous Composite Laminates

16 Oct 2020 | Contributor(s): Johnathan Goodsell

After more than 30 years of careful experimental investigation and exhaustive development of discrete damage analysis methods including integrated computational mechanics methods, our community knows a great deal about how discrete defects such as matrix cracks and defect growth (e.g....

Development of Fiber Microstructure during Processing of Discontinuous Fiber Reinforced Composite Products

19 Apr 2024 | Contributor(s): Johnathan Goodsell

Discontinuous fiber-reinforced composites are a special subcategory of composite materials that are used, due to the ability to process them into parts and structures of complex shape in an automated fashion via compression and injection molding, as well as extrusion processes. Discontinuous...

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

Although carbon fiber reinforced polymer (CFRP) composites have been used extensively in many aerospace structures such as Boeing 787 and Airbus 350, low-cost and high-rate production CFRP are highly demanded for next-generation single-aisle commercial aircraft. Competition has been increasing...

Fibrous Shell Approach and 3D Second Gradient Modeling for Textile Composite Draping

10 Dec 2021 | Online Presentations | Contributor(s): Johnathan Goodsell

Composite manufacturing processes are often complex and process simulation is a way to avoid costly trial-anderror development. Simulations of composites textile reinforcements draping use shell finite elements for which the bending behavior is very particular. The fibrous composition of the...

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...

Injection Overmolding Manufacturing Process Simulation

29 Jun 2017 | Online Presentations

Injection over-molding or hybrid molding is a high-rate composites manufacturing process for fabrication of structural components with complex geometries.  The structural backbone is provided by a continuous-fiber woven prepreg while the geometric complexity is realized via injection...
