Continuous Composites Enhances FEA Simulation for Anisotropic Composites

Continuous Composites (CCI) has recently been granted a substantial Tactical Funding Increase (TACFI) contract worth $1.9 million by the U.S. Air Force as part of an initiative to innovate in the field of composite materials. The contract aims to enhance the Finite Element Analysis (FEA) tool specifically for Continuous Fiber 3D Printing (CF3D), which is crucial for developing anisotropic composite materials.

What Are Anisotropic Composites?

Anisotropic composites are materials exhibiting different strengths and properties depending on the direction of the applied load. This characteristic is primarily determined by the fiber orientations within the composite. Unlike isotropic materials—such as metals—whose mechanical responses are uniform in all directions, anisotropic composites offer unique challenges for simulation and analysis. This disparity creates a pressing need for advanced tools that can accurately predict their behavior under various conditions.

Addressing the Simulation Gap

Current FEA solutions are inadequate when it comes to simulating anisotropic materials, often relying on simplified models that treat composite layers as uniformly behaving materials. Steve Starner, CEO of Continuous Composites, highlighted the limitations of existing technology: “Existing software only assigns a single directional property to each layer of composite material, but CF3D’s fiber steering requires a more dynamic approach.”

The new FEA tool will leverage CF3D toolpath data to create mesh representations that reflect accurate fiber orientations. By improving material behavior predictions, this tool aims to enhance the reliability and efficiency of designing complex composite parts essential for flight and defense applications.

A Leap Forward

With a planned development timeline stretching from November 2024 through August 2026, CCI is collaborating with industry experts to optimize this advanced simulation tool. The integration of this new FEA capability into CF3D Studio™, CCI’s proprietary software, will allow engineers to forecast material properties and performance before physical prototypes are even tested.

This innovation promises to significantly speed up the development process, saving time and resources, while also increasing the safety and efficacy of aerospace and defense technologies. It represents a monumental step in transforming CF3D technology from a straightforward manufacturing method to a full-fledged design-to-performance solution.

Promising Applications

The practical applications of this technology extend across several sectors, particularly in aerospace, defense, and unmanned aerial vehicles (UAVs). The ability to accurately simulate how anisotropic materials will react under real-world conditions is critical for industries where safety and performance are paramount. CCI’s work could lead to the next generation of lightweight, high-performance structures that revolutionize these sectors.
