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?

As an experimentalist I look at this problem by making a mental list. Maybe start with how can I get rid of the kinetic energy? Deform or bend something? Compress something a lot denser, like a spring? Turn it into heat? Turn it into mechanical energy and shake something outside the box? Frequency shift? Cancel with superposition using another source of energy? Reflect/refract around a protected area? Slow down the pressure change with screens and filters? etc. Then start refining - look for simple solutions or ways to use materials, techniques, devices. Thought experiments then start testing. –  C. Towne Springer Apr 25 at 8:50

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.
