Duocel® Energy Absorbers are designed to be utilized in a variety of applications, including energy absorbers, crumple zones and impact protection.
Our patented aluminum foam permanently deforms and compresses providing the ideal stress curve.
Our universal design allows simple integration onto existing products.
Benefits of a Duocel® Energy Absorber include:
High strength-to-weight ratio – Duocel® is lightweight due to its porous structure while maintaining many of the properties, including strength, of its parent material (e.g., aluminum).
Controlled strength and stress-strain behavior – The properties of Duocel®, such as relative density and heat treat condition, can be tailored for specific mechanical performance requirements.
Isotropic compression – Duocel® deforms and compresses uniformly regardless of the load/impact direction.
Resistant to harsh environments – Duocel® is made from robust materials that can withstand extreme temperatures, humidity, chemicals and liquids, atmosphere/vacuum conditions, etc.
No sharp spike in yield strength – This behavior can be mitigated by adjusting the properties of Duocel®.
Custom shapes to optimize size and weight – Duocel® can be fabricated to a specific geometry to conform to design requirements.
The plot below demonstrates the forces applied during an impact. Our patented metal foam’s structure is not only omnidirectional, but also extends the “Ideal Energy” zone:
