Abstract: The invention provides a porous hybrid matrix membrane support having at least one porous mesh layer of mesh densified to form a membrane mesh support and at least one porous filament layer of filaments that are generally non-woven, densified to form a membrane filament support. The filament layer is densified to provide a sufficiently small crevice depth in the membrane filament support that can help protect a membrane layer on the membrane filament support from rupturing. The membrane mesh support and the membrane filament support with micro-smooth surfaces can be integrally joined by diffusion bonding to resist separation across the adjoining surfaces. The combined, diffusion bonded support of both types of layers provide structural support sufficient for high pressures and provide substantial uniform permeability across the face of the structural support.
