    摘要: The preparation of three dimensional skeletal structures using the step of deforming rounded beads to form a mold or matrix is described. A filler material is introduced and then rigidified to form the skeletal structure. The deformable beads are composed of materials which deform upon compression or expansion due to pressure from adjacent beads and included, for instance, metals, waxes, salts, polymers, and ceramic compositions in their plasticly deformable states. The filler material which rigidifies to form the skeletal structure can be composed of solidifiable materials such as metals, polymers, or ceramic compositions. The solid material volume of the skeletal structure so formed upon removal of the beads is between about two percent (2%) to twenty percent (20%) of a corresponding volume of a non-skeletal solid material. The corresponding porosities representing the interconnected void volumes are between about eighty percent (80%) and ninety-eight percent (98%) of a corresponding volume of a non-skeletal solid material. The skeletal structures so formed can be flexible, semiflexible or rigid and are useful as heat exchangers, catalyst supports, distillation tower packings, filters and the like.

    摘要: An improved method is described for thermally bonding contacting pieces of a thermoplastic material provided in a variable volume confined space surrounded by a combustible gas. The combustible gas is ignited and explosion diffused externally of the pieces of thermoplastic material and thus heats the pieces without damage sufficiently to produce interbonding when the heated pieces are compacted in the confined space. The heated pieces are compacted isostatically or non-isostatically using various apparatus which reduce the volume of the confined space. Preferably a moveable piston is provided in a cylinder to form the confined space for the pieces. The driving means for the piston can be a combustible gas which is ignited or non-combustible gas under pressure or a resilient means or other mechanical means. The products of the method are in the form of a porous mass composed of the interbonded pieces which are undamaged by the explosion.

    摘要: A body of a specially prepared, porous vitreous carbon which does not crack or substantially change in electrical resistance with time when heated to elevated temperatures in air and which is used in a method or apparatus to heat a fluid stream flowing in the pores of the body as a result of natural convection or pumping of the fluid is described. The body is composed of electrically conductive rigid, interconnected and multidirectional continuous strands of vitreous carbon forming a rigid porous, three dimensional skeletal structure. The body as an electrical resistance element has current conductive paths between at least two regions; is shaped to provide particular cross-sections along the conductive paths; and has electrical connector means attached at the regions of the body so that current can be distributed through the body. The electrical resistance element is particularly useful as a heating element for air flowing through the pores in electrically powered room space heaters, hair dryers, hand dryers and the like and can also function as a self-cooling resistor. In a like manner, electromagnetic energy is used to heat a body of the porous vitreous carbon so as to heat a fluid stream flowing through the pores.

    摘要: A reticulated anisotropic porous carbon structure composed of bent or crimped interconnected and continuous strands is described. The structure is isomorphic with the compression bent strands of the flexible reticulated polyurethane structure from which it is derived. The structure compression can be sufficient for interbonding of the bent strands which overlay each other or the bent strands can be essentially free of bonding to adjacent strands. The carbon structure is derived by providing a compressed reticulated anisotropic polyurethane structure composed of the bent strands which is then infused with a liquid thermosetting resin or resin solution or resin precursor, removing any excess liquid resin or resin precursor or resin solution from the surfaces of the strands; and then carbonizing the infused strands at an elevated temperature. The reticulated carbon structures so formed are relatively unreactive, even at very high temperatures, under reducing or neutral conditions and are particularly useful as corrosive and high temperature material filters, battery electrodes, porous catalysts or catalyst supports as well as for making carbide containing articles by infusion of the pores with a carbide forming metal or cladding thereof such as with carbide or nitride coatings by chemical vapor deposition and the like.

    摘要: A rapid method for forming vitreous carbon foams from flexible polyurethane foams having membranes dividing contiguous cells, which faithfully reproduces the geometry of the uncarbonized polyurethane foams, by infusing the polyurethane foams with substantially unresinified or unpolymerized furfuryl alcohol which is capable of resinification at temperatures above room temperature is described. An important step in the method which permits rapid carbonization without cracking and which is essential to faithful foam geometry reproduction is the substantial removal of the liquid non-infused furfuryl alcohol from the polyurethane foam surfaces after the infusion or swelling step. The carbonized foam is in the form of vitreous, disordered or glassy carbon and is particularly useful for corrosive and/or high temperature applications such as insulation, corrosion resistant chemical processing components and the like.
