The United States Department of Defense tested HJ3-backed technology to wrap a structure in carbon fiber and test it’s strength against a violent explosion.
HJ3 conducted testing to demonstrate the performance of the BlastSeal™ System. Two un-reinforced concrete masonry walls were constructed within a larger containment structure. BlastSeal™ was applied to the interior and exterior of the right side.
Detonation of explosive created a crater that was approximately 108 inches in diameter with a maximum depth of 21 inches. The control wall was completely destroyed.BlastSeal™ Retrofitted wall remained intact, and no debris of any kind was found in the interior space behind the retrofitted wall.
Maximum pressure exerted on the exterior face of each wall was 178 psi; sensor located in the interior space behind the retrofitted wall recorded a peak pressure of 1.46
