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

19 Apr 2024

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...

Bottom-up Composites Materials Design for Multifunctionality

02 Apr 2024 | Contributor(s): Ajit K Roy

There are ample of evidence of materials hybridization at scale, even in nature, yields optimal respond to specific functions. In structural materials, hierarchical materials hybridization accounting for defects or porosity would offer optimal performance at reduced materials mass. Similar...

01 Mar 2024 | Contributor(s): Jan-Anders Mansson

The use of new materials to enhance sports performance is inevitable, and the development of sports equipment and apparel stands as a significant industry. Frequently, cutting-edge materials like composites find extensive use in sports equipment and are often introduced on the playing field long...

US-COMP: Next Generation of Composites Materials for Crewed Deep Space Missions

15 Dec 2023 | Contributor(s): Greg Odegard

Current state-of-the-art composite materials are not light/strong enough for crewed missions to Mars and beyond. Structural components of deep space vehicles require lighter/stronger materials for fuel efficiency. The NASA Space Technologies Research Institute (STRI) for Ultra-Strong Composites...

Structural Self-sensing Based on Measuring the Resistance, Capacitance or Inductance of the Structural <aterial, Without Sensor Incorporation

06 Nov 2023 | Contributor(s): Deborah Chung

Structural self-sensing refers to a structural material sensing itself without sensor incorporation. Compared to sensor incorporation, advantages include low cost, high durability, large sensing volume and the mechanical properties being not degraded. The self-sensing ability makes the structural...

Composites Forming Simulations - on Physics & Data, Accuracy & Applicability

23 May 2023 | Contributor(s): Remko Akkerman

Composites Forming processes, in particular stamp forming, offer the potential of high volume manufacturing of light weight structural parts. Such parts need to be designed with the process and its requirements in mind, in order to prevent process induced defects such as wrinkling or poor...

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...
