    摘要: An exothermic cord, foil, or ribbon is produced by first cold drawing individual round wires of the constituent materials under a cover gas. The cold drawing operation yields a clean surface that is free of oxidation and other contaminants. Next, the constituent wires are brought together and twisted, cold drawn, swaged, and/or friction welded to create a unitary cord exhibiting intimate contact between the constituent materials. The unitary cord may then be used directly or further shaped to a desired form and/or thickness. By controlling the size ratio between the cross-sections of the constituents, a degree of control can be exercised over the exothermic reaction characteristics. The unitary cord, once formed, can be coated with braze and/or flux materials to aid in a subsequent joining operation. Multiple cords can be woven together to form a cloth structure. The exothermic assembly can be applied in the field of gaskets to permanently affix opposing surfaces together, such as affixing a cylinder head in an operative position over a cylinder block.

    摘要: A method and apparatus is provided for forming an in-mold cured brake pad (16). A mold (24) includes sidewalls (28) through which a window (24) made from a generally lossless material such as alumina is formed. Microwaves (42) are directed through the window (46) and into the die cavity (26) of the mold (24) to provide supplemental heating and thereby accelerate the manufacturing cycle time. The friction material composition is tuned by adding an effective quantity of titania or other suitable agent which has the advantage of moving the absorption band for the heat-curable material into the standard band (50) of the microwaves (42) produced by a low-cost magnetron (40), and also of self-regulating the absorption characteristics of the heat-curable material so as to reduce or eliminate the tendency to thermal runaway.
