I am trying to find a way to limit the effect that detonation of an explosive gas, introduced into a confined space would have when detonated. Can one introduce some form of panelized material or construction that would work to minimize the effect of the initial explosion and shockwave resulting from such?
The energy must be spread in time and space. It can be absorbed in a phase transition so that PV (101.325 J/liter-atm) becomes latent heat (immersion in fire-fighting foam blunts explosions). Thinking long term, Google "foamed aluminum." The tough matrix collapses in on itself, absorbing energy in ductile deformation. Give it a tensile backing like tightly woven Kevlar or Spectra, perhaps in its own tough matrix.
