A method of manufacturing and the resultant reticulated open cell carbon foam with a controlled aspect ratio between 0.6 to 1.2 throughout the body of the foam billet by controlling the exothermic reaction of the resin system below the decomposition temperature of the foam.

Method for producing controlled aspect ratio reticulated carbon foam and

A method of producing an acoustic baffle/catalyst foam support material and the resultant material. A polyurethane open cell foam material is provided having a density between 10-100 ppi. The polyurethane foam is infiltrated with a resin material to produce an impregnated foam. The impregnated foam is pyrolized to form a carbon skeleton forming a carbon foam. The carbon foam skeleton is coated with one or more of the following group of materials to a relative density of five to thirty five (5-35) percent, the group of materials being SiC, Si.sub.3 N.sub.4, MoSi.sub.2 or high temperature metal.

Foam catalyst support for exhaust purification

An airbag assembly including an inflatable airbag, an ignitable propellant charge for generating inflating gas and a filter between the interior of the airbag and the propellant charge. The filter comprising a porous carbon foam substrate coated substantially throughout with a thermally and structurally stable material which has been formed in situ by chemical vapor deposition techniques.
