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....

Demystifying Composites Simulation for Performance

28 Jul 2016 | Contributor(s): Ali Roumani

The presentation given in IACMI Tutorial session before the 2016 Summer Members Meeting. It tried to explain in layman terms modeling and simulation, and composites, pointed out the barriers we need to overcome to reap full benefits of simulation for composites innovation. 

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...

Emerging Role of Process Models & Simulations in Composites Manufacturing

07 Dec 2020 | Contributor(s): Johnathan Goodsell

This talk will highlight the ever increasing benefits of process modeling in Composite Manufacturing processes. First, the use of science base approach of materials processing, which integrates material parameters with transport phenomena at various scales during manufacturing to create...

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

08 Feb 2023 | 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 | 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 | 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...

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...
