    摘要： 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.In accordance with the invention, RCMs are fabricated by a series of mechanical deformation steps. 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. This severe initial deformation substantially eliminates the tendency of deformed layers to delaminate and eliminates the necessity of using specially cleaned metal layers. 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. The resulting product is a controllable, locally layered reactive composite material (LLRCM) that can be fabricated quickly and is useful in a wide variety of applications.

    摘要翻译： 申请人已经发现了新的复合材料，并开发了各种新的制备反应性复合材料（RCM）的方法和控制与许多新的或改进的应用相关的材料的性质和特性的方法。 该专利申请涉及使用机械变形制造反应性复合材料的新的和改进的方法，并使得具有可控，可预测的特性的这种材料。 该应用也针对所得材料的有用应用。 根据本发明，通过一系列机械变形步骤制造RCM。 在第一变形步骤中，反应层和/或颗粒的组件塑性变形以将其横截面积减小一半以上。 这种严重的初始变形基本消除了变形层分层的趋势，并且消除了使用特别清洁的金属层的必要性。 变形的片材的一部分被堆叠或弯曲成新的组件，并且新的组件然后变形。 组装和变形的步骤重复足够次数，使得所得到的材料仅局部分层，但具有相对均匀的反应速度和通过本文得到的随机模型可预测的发热特性。 所得到的产品是一种可控制的局部层状反应性复合材料（LLRCM），可以快速制造，并可用于各种应用。
