Report on Composite Metal Foam for Safer Hazardous Material Transportation and its Contribution to Sustainable Development Goals

Executive Summary

A recent study highlights the significant potential of Composite Metal Foam (CMF) to enhance the safety of hazardous material transportation. The material’s superior ability to absorb impact energy at a lower weight than conventional steel presents a direct pathway to advancing several United Nations Sustainable Development Goals (SDGs). This report outlines the study’s findings and analyzes the role of CMF in promoting resilient infrastructure (SDG 9), creating safer communities (SDG 11), protecting public health (SDG 3), and encouraging responsible production patterns (SDG 12).

Technological Innovation: Composite Metal Foam (CMF)

Material Properties and Composition

Composite Metal Foam is an advanced material with properties highly conducive to safety and sustainability applications. Its key attributes include:

• Lightweight Structure: CMF consists of hollow metallic spheres embedded within a solid metallic matrix, resulting in a significantly lower density than solid metals.
• High Energy Absorption: The material demonstrates a remarkable capacity to absorb compressive forces and impact energy, making it exceptionally strong and durable.
• Superior Thermal Insulation: CMF provides better insulation against high heat compared to conventional steel and maintains its strength when exposed to high temperatures.

Puncture Resistance Test Findings

To validate its performance, CMF was subjected to rigorous testing simulating a high-impact event on a railroad tank car.

1. Test Parameters: A 300,000-pound ram car, fitted with a six-inch square steel indenter, was accelerated to 5.2 miles per hour, generating 368 kilojoules of force.
2. Baseline Result: In a control test, the indenter created a large puncture in a standard steel plate used for tank cars.
3. CMF Result: When a 30.48 mm thick layer of CMF was placed on the indenter, it absorbed the vast majority of the impact force. The ram car bounced off the steel plate, leaving only a minor dent and preventing any puncture.

A computational model has also been developed to optimize the thickness of CMF required for specific applications, ensuring maximum safety and material efficiency.
