Abstract: Composite materials comprising at least 60 volume %, preferably 70 volume %, of particles of finely powdered filler material in a matrix of poly(arylene ether) polymer material are made by forming a mixture of the components, forming the required bodies therefrom, and then heating and pressing the bodies to a temperature sufficient to melt the polymer and to a pressure sufficient to disperse the melted polymer into the interstices between the filler particles. Surprisingly these polymer materials can only be effective as bonding materials when the solids content is as high as that specified, since with lower contents the resultant bodies are too friable. This is completely contrary to accepted prior art practice which considers that composites are progressivly weakened as the solids content is increased, so that such content must be limited.

Abstract: A load bearing-metal panel and stucco substrate cooperates with adjacent panels to form load bearing studs that are interconnected by a metal lath stucco substrate to which stucco can be applied, each panel being generally in the form of a channel in which insulation can be placed, whereby a wall structure can be formed by adjacent placement and interconnection of panels.
