Flame Resistant Crash Test Dummy Calibration Honeycomb Energy Absorber of Predictable Crush Profile

Flame Resistant Crash Test Dummy Calibration Honeycomb Energy Absorber of Predictable Crush Profile

 
Pasia Industries, as a leading manufacturer of honeycomb energy absorbers, specialize in producing high-performance aluminum honeycomb cores that convert kinetic energy into controlled, predictable crushing forces.

Our Flame Resistant Honeycomb Energy Absorber is purpose-engineered for crash test dummy calibration—specifically the neck flexion/extension certification tests required under US Code of Federal Regulations (Part 572, Subpart E) and European ECE Regulations . These precision aluminum honeycomb blocks generate the controlled deceleration pulse essential for verifying Anthropomorphic Test Device (ATD) performance, ensuring repeatable, regulation-compliant calibration results.

The product combines predictable crush profile characteristics with flame-resistant material properties, making it suitable for testing environments where fire safety standards must be met.

Predictable Crush Profile – Engineered for Calibration Precision

The Science of Predictable Energy Absorption

When a load is applied to aluminum honeycomb, it undergoes plastic deformation through controlled cell wall buckling, converting kinetic energy into internal work at a constant force across the crushed thickness . This results in a linear, predictable force-displacement curve—the foundation of reliable dummy calibration.

Our energy absorbers deliver:

· Consistent crush strength tolerance within ±10% of rated value

· Crush stroke exceeding 70% of part thickness before densification

· Minimal rebound – virtually all impact energy converted to deformation, not returned to the system

· Elimination of peak loading via pre-crush option (static triggering)

Calibration Application Context

The neck extension/flexion test requires a precisely characterized deceleration pulse. As specified in ASTM F3016-14, the impactor nose must have zero stored energy before impact and no elastic rebound after impact . Aluminum honeycomb uniquely satisfies this requirement, providing a "crush and stop" behavior that foam or spring-based systems cannot replicate .

Flame Resistance – Safety Without Compromise

This product incorporates flame-resistant treatment or alloy selection appropriate for testing environments where:

· Aerospace cabin safety standards apply (FAA burn test requirements)

· Automotive test labs require fire-safe materials

· Defense and military testing protocols mandate flame retardancy

The flame-resistant properties do not compromise the predictable crush mechanics – the core retains its certified crush strength and deformation characteristics while meeting applicable fire safety classifications.
