Thin-Wall Composite
Echo Lite.
Validation
Shock-tube test at 20 psi.
Here 20 psi is peak blast overpressure, well beyond the roughly 10 psi that collapses ordinary buildings. Both construction options were put in the tube: the composite-shell panel (1.25 in.) and the PVC-formed panel (3.5 in. finished), each cast around a fiber-reinforced high-strength mortar core rated to 10,000 psi in compression.

20 psi
Peak blast overpressure. Both panels held with no breach: the composite-shell panel deflected 10 in. and the PVC-formed panel 6 in., each staying within the allowable response limit and returning to place.
Test Apparatus
1–40 psi
BakerRisk shock tube, La Vernia, TX. A shock tube fires a controlled blast wave down a barrel at a mounted panel. Panels up to 12 × 12 ft. Also used for Echo Arch.

Hydrocode Modeling
20 psi blast on a 6-story structure.
Side-by-side hydrocode blast simulations, a physics model that tracks how the shock wave moves through the structure. Same charge, same standoff (the distance from the charge to the building), same building. The only variable is whether the first two floors are clad in Echo Lite.
Conventional 6-Story
Structural failure propagates through the lower floors and compromises the building.
Echo Lite Cladding
Echo Lite absorbs the incident pulse. Energy is redirected and the upper structure remains intact.
Hydrocode blast simulation. 20 psi peak incident overpressure.
