Designing with Continuous Fiber Materials
When extreme lightweight requirements meet ultimate performance needs, continuous fiber reinforced materials are the solution of choice. Optimized weight-performance ratios are just as important in the aerospace industry as in transportation, sports, racing, and many other applications. Innovative composite designs using carbon fibers and other reinforcement materials meet performance, weight, and quality requirements while considering economic manufacturing. The holistic simulation of continuous fiber composites is an important building block to tailor products to individual requirements. Altair composite solutions make this happen quickly and reliably.
Master Process-dependent Material Behavior
Composite material behavior is defined as components are manufactured. Analyze composite structures at the required level of detail with Altair solutions. Develop and simulate multiscale heterogeneous material models with Altair® Multiscale Designer®.
Assure manufacturability with draping and forming simulation for sandwich and multilayered laminates.
Optimize Composite Laminates
Tailor composite properties throughout a structure to optimize performance potential.
Manufacture to design geometry constraints to meet a structure’s aerodynamics, ballistics, or other performances.
Explore increased design freedom to exploit the true potential of composite materials with Altair optimization technology and processes developed with industry leaders.
From Ideation to Composite Certification
Successful composites design requires a comprehensive composite design strategy.
Using a material model development framework, integrated manufacturing, structural simulation, composite design optimization, and composite design certification, Altair’s composite solutions enable production-ready high-performance designs to outperform project milestones.

Accelerate Composites Design to Production
Successful composites design requires a holistic design strategy. Altair offers a comprehensive suite of design and analysis tools that efficiently design composite structures, convert metal designs to composites, optimize for performance and weight, and intuitively explore variations in design configurations. Altair has more than 35 years of experience designing, analyzing, and optimizing composite structures and can partner with customers in a variety of ways to achieve success in using composite materials.
Composite Design Certification
The efficient assessment of composite structures requires an effective mix of analytical methods and FEA analyses, particularly in the early design phases.
The Altair® HyperWorks® Composite Stress toolbox allows early design certification.
Plan required margins of safety and reserve factors against given design criteria. Probabilistic laminate analyses and failure hypotheses for first ply failure analyses, sandwich failure modes, and delamination allow an efficient and early composite design certification
Predict Ultimate Failure Behavior
The ultimate failure behavior is an essential part of the design process, especially in applications with strict safety requirements. To predict fracture, buckling, or delamination of continuous fiber composites, numerical descriptions of material must account for this and represent these important elements accurately.
When quasistatic loading conditions are investigated Altair® OptiStruct® predicts accurate composite failure.
Running impact analysis with Altair® Radioss® for events such as bird strikes, crashes, and drops provides accurate predictions of multiphysics behavior. Users can improve prediction quality of component behavior with common failure models and customization of failure models for unique requirements.
Material Data and Characterization
Availability of material data is a major bottleneck in simulating composite structures. Material suppliers’ datasheets or handbook values do not represent actual properties resulting from individual manufacturing processes. Doing a complete material characterization through a test campaign is often costly and time consuming.
Altair® Material Data Center™ enables designers, engineers, and scientists to browse, search, and compare materials in a standalone application or through the interface of their simulation and optimization tools.
Multiscale Designer is a comprehensive framework to develop highly-predictive and computationally-efficient material models for all material behaviors ranging from homogeneous isotropic to heterogeneous anisotropic. Multiscale Designer reduces the time and cost associated with the development of highly predictive material models with minimal experimental data requirements.
A Flexible Approach
In today’s business environment, you need a partner that can work with you in a flexible manner. With Altair One™, you have access to every Altair product and the power to solve on any scale.
