High Strength, Cylindrical Energy Absorber
Plascore Aluminum Tubular Core AltuCore™ is a lightweight, high-strength core manufactured in an annular cylindrical shape which is well-suited for single-use energy absorption applications. AltuCore™ yields at a constant force providing reliable and consistent energy absorption for applications with in-axis loading conditions.
Features
- Energy absorption in a cylindrical shape
- High crush strength-to-weight ratio
- Efficient constant force crush curve
- Wide range of strengths available
- Typical crush stroke is 60% of length
- Excellent moisture and corrosion resistance
- Elevated use temperatures
Applications
Aerospace
A lightweight single-use energy absorber for attenuating impacts, controlling maximum loads, and over-travel protection.
Defense
Can serve as a crushable member to mitigate dynamic events.
Dynamic Testing
For high G load testing of components.
Industrial Safety
Provides efficient high-load drop or overload protection to prevent equipment failure.
Shipping Protection
Precise crush strength and high service temperatures facilitate use in many environments with minimal impact on the shipping weight.
Transportation
Attenuates impact in applications where lightweight, high-performance energy absorption is critical for safety.
Availability
AltuCore™ is custom manufactured in a wide range of strengths and sizes. Available as load certified in precrushed form or in stock lengths.
Properties
A range of static crush strengths from 1000 – 8000psi can be manufactured.
- Dynamic crush strengths can be 10% – 40% higher depending on strength and impact velocity. AltuCore™ should be evaluated by dynamic test in the final configuration to verify dynamic performance.
- Crush strokes as high as 70% are available, decreasing to 55 for higher strength core.
- AltuCore™ will crush and fold upon itself uncontained to strengths of 2500psi. Higher strengths should be contained within a cylinder, crushed into a cap, or wound with a composite wrap for best performance.
