Design and simulation for composite materials

Composite materials are transforming modern engineering. By combining two or more distinct materials, engineers create structures that are stronger, lighter, and more durable than anything a single material can achieve alone.

What are composite materials?

Industries worldwide are racing to adopt composites — driving demand for faster, smarter ways to design and validate these high-performance materials.

Engineers harness the power of design and simulation to unlock the full potential of composite materials — from carbon fiber reinforced polymers to advanced glass fiber structures. By defining precise material properties, fiber orientations and layup sequences, teams simulate real-world mechanical, thermal and dynamic loads before a single prototype is built. Simulation tools reveal stress distributions, predict failure modes and expose structural weaknesses early — slashing development costs and accelerating time to market. Across aerospace, automotive and energy industries, design and simulation empowers engineers to build lighter, stronger and smarter composite components with confidence.

Navigating composite complexities

Composite materials offer incredible advantages, yet their unique properties introduce significant engineering and manufacturing challenges. We understand these critical hurdles and are equipped with innovative approaches to help you overcome them effectively.

Increasing material complexity

Unlike metal, composites behavior varies with fiber orientation, layup sequence and material combinations. Their anisotropic nature complicates predicting structural response, demanding advanced modeling and specialized expertise.

Structural validation becomes difficult

Validating composites is more complex than with traditional materials, involving multiple failure modes and requiring both extensive testing and simulation to align virtual models with real-world performance.

Manufacturing variability

Composites are highly sensitive to manufacturing. Resin distribution and fiber placement can cause defects—voids, delamination or warping—that affect structural performance. Consistent production remains a costly challenge.

Composite design and simulation software solutions

Advanced design and simulation software tackles the toughest composite engineering challenges head-on. From early-stage design through to manufacturing, it empowers engineers to move faster, simulate smarter, and build better composite products with confidence.
