20090035542 | LOW TEMPERATURE REACTIVE COMPOSITE JOINING - Reactive foils and their uses are provided as localized heat sources useful, for example, in ignition, joining and propulsion. An improved reactive foil is preferably a freestanding multilayered foil structure made up of alternating layers selected from materials that will react with one another in an exothermic and self-propagating reaction. Upon reacting, this foil supplies highly localized heat energy that may be applied, for example, to joining lawyers, or directly to bulk materials that are to be joined. This foil heat-source allows rapid bonding to occur at room temperature in virtually any environment (e.g. air, vacuum, water, etc.). If a joining material is used, the foil reaction will supply enough heat to melt the joining materials, which upon cooling will form a strong bond, joining two or more bulk materials. | 02-05-2009 |
20090065554 | Methods and device for controlling pressure in reactive multilayer joining and resulting product - The invention includes a method of joining two components. The method includes providing at least two components to be joined, a reactive multilayer foil, and a compliant element, placing the reactive multilayer foil between the at least two components, applying pressure on the two components in contact with the reactive multilayer foil via a compliant element, and initiating a chemical transformation of the reactive multilayer foil so as to physically join the at least two components. The invention also includes two components joined using the aforementioned method. | 03-12-2009 |
20090178741 | Method Of Making Reactive Composite Materials and Resulting Products - Novel reactive composite materials and associated methods for making the same which are pertinent to numerous new or improved applications. The method for making the reactive composite materials utilizes mechanical deformation to manufacture such materials with controlled, predictable characteristics. In the first deformation step, an assembly of reactive layers and/or particles is plastically deformed to reduce its cross sectional area by one-half or more. Portions of the deformed sheets are stacked or bent into a new assembly, and the new assembly is then deformed. The steps of assembly and deformation are repeated a sufficient number of times that the resulting materials are only locally layered but have relatively uniform reaction velocity and heat generating characteristics predictable by stochastic models derived herein. | 07-16-2009 |
20100175756 | Method For Bonding Of Concentrating Photovoltaic Receiver Module To Heat Sink Using Foil And Solder - A method for bonding a concentrating photovoltaic receiver module to a heat sink using a reactive multilayer foil as a local heat source, together with layers of solder, to provide a high thermal conductivity interface with long term reliability and ease of assembly. | 07-15-2010 |

20110027547 | Methods of making reactive composite materials and resulting products - Applicants have discovered new composite materials and have developed a variety of new ways of making reactive composite materials (RCMs) and methods of controlling the properties and characteristics of the materials that are pertinent to numerous new or improved applications. This patent application is directed to new and improved ways of making reactive composite materials using mechanical deformation and making such materials with controlled, predictable characteristics. This application is also directed toward useful applications of the resulting materials. | 02-03-2011 |
20110070460 | Reactive composite material structures with electrostatic discharge protection and applications thereof - Applicants have discovered that electrostatic discharge (ESD) may, in some circumstances, result in current densities sufficient to ignite unprotected reactive composite materials. They have further discovered that a reactive composite material (RCM) can be protected from ESD ignition without adversely affecting the desirable properties of the RCM by the application of conducting and/or insulating materials at appropriate locations on the RCM. Thus ESD-protected RCM structures can be designed for such sensitive applications as ignition of propellants, generation of light bursts, and structural materials for equipment that may require controlled self-destruction. | 03-24-2011 |
