Stahlin Non-Metallic Enclosure survives impact during bridge detonation

Stahlin Non-Metallic Enclosure survives impact during bridge detonation.

Crews used explosives to demolish part of the Long Island Bridge in Boston Harbor. In the detonation video posted below, about 35 seconds into the video, you can see that the Stahlin non-metallic enclosure remained intact after the explosion.


How is this possible?

What specifiers may not know is that even though stainless steel has high strength, it exhibits low toughness—the resistance level of a material that can be damaged on impact. The low toughness of a metal enclosure causes it to easily dent. When a steel enclosure is dented, the integrity of the box can be compromised.

With improvements in non-metallic composites, fiberglass enclosures are designed for both high strength and toughness due to additives and fiber reinforcements. Thus, they can withstand sudden impact while maintaining their shape. This is why Stahlin’s enclosure was able to survive the detonation.

In addition to the prior video proof demonstrating the impact resistance of non-metallic materials, Stahlin has put together a brief video further demonstrating how non-metallic enclosures outperform metal alternatives in resisting impact damage.
