Lightweight Metal Foam Structures

What are lightweight metal foam structures?

Duocel® Lightweight Structures are solid ligament, open cell foam structures, often with a solid component to increase strength and provide a flush interfacing surface.  These structures offer exceptional strength-to-weight ratios and are fully customizable, making them ideal for applications where weight savings and mechanical performance are critical.

Why Choose Duocel® for Lightweight Structural Applications?

Duocel® foam stands out due to its unique combination of properties:

  • High Strength-to-Weight Ratio: The open-cell structure ensures minimal weight without compromising structural integrity.
  • Customizable Properties: Adjustable parameters like relative density and pore size allow tailoring of mechanical properties to specific application needs.
  • Isotropic Behavior: Uniform properties in all directions ensure consistent performance under multidirectional loads.
  • Thermal and Chemical Stability: Suitable for extreme environments, Duocel® maintains performance under high temperatures and in corrosive conditions.
  • Integration Flexibility: Easily incorporated into assemblies through bonding, brazing, or mechanical fastening.

Applications of Duocel® Lightweight Structures

Duocel® foams are utilized in a wide range of applications where lightweight and high-performance materials are essential:

  • Aerospace: Structural components, impact protection, and thermal management systems.
  • Defense: Lightweight armor, blast mitigation structures, and structural panels.
  • Industrial: Lightweight, high strength support structures are often built from foam sandwich panels. Particularly in high-temperature processing equipment and filtration systems.
  • Space: Lightweight components, sensor protection, and micrometeorite protection can be implemented with radiation protection or thermal transfer in a single product!

Customization and Fabrication

ERG Aerospace offers Duocel® foams with customizable features to meet specific design requirements:

  • Pore Size (PPI): Available in various pores per inch (PPI) to control permeability and surface area.
  • Relative Density: Adjustable to balance weight and mechanical strength.
  • Material Selection: Most support structures are built with aluminum foam and supporting panels
