摘要： PROBLEM TO BE SOLVED: To provide a technology that can manufacture a compound material with high thermal conductivity in which high thermal conductivity performance is maintained well.SOLUTION: A mixed material 16 of a matrix metal 14 and a carbon fiber 15 as shown in Fig.(b) is sintered in a hot press-sintering furnace 20 as shown in Fig.(c). Then, each piece of the matrix metal powder 14 is linked together each other by diffusion bonding actions. As a result, the movement of the carbon fiber 15 is restricted to maintain the diffusion state. When sintering is performed, the area to contact with oxygen becomes extremely small, so that the influence of oxidization is lightened. A primary molding is a sintered product of a matrix metal in which the carbon fiber is pinched between the matrix metallic powers jointed by diffusion. Even if external power is applied to the primary molding, the matrix metal exhibits a protective action, so that the carbon fiber is not cut off. Consequently, the high thermal conductivity performance is maintained.
摘要翻译：要解决的问题：提供一种能够制造高导热性能良好地保持高导热性的复合材料的技术。如图（c）所示，在热压烧结炉20中烧结如图（b）所示的基体金属14和碳纤维15的混合材料16。然后，通过扩散接合动作使基体金属粉末14的每一个彼此连接。结果，限制碳纤维15的移动以保持扩散状态。当进行烧结时，与氧接触的区域变得非常小，从而减轻了氧化的影响。初级模制品是基质金属的烧结产品，其中碳纤维被挤压在通过扩散结合的基体金属力之间。即使外部电力施加到初级模制品，基体金属也具有保护作用，因此碳纤维不被切断。因此，保持高导热性能。版权所有（C）2012，JPO＆INPIT
