    • A component made of electrically insulating material with a detection structure for mechanical damage such as cracks is disclosed. The detection structure is a conductor. The electrical properties of the detection structure are modified as more and more cracks are formed such that the component will be replaced in time before breaking. The electrical conductor is formed by particles that are in contact with each other and have a metallic surface such that an electrical conductor is created which is particularly sensitive to mechanical damage, thus rendering the detection structure highly sensitive. Furthermore, if the metallic surface is produced merely by cladding the particles while the inside of the particles is made of the same material as the component, a conductor featuring an adapted thermal expansion behavior is created for components that are subject to great thermal stress, e.g. heat shield panels.
    • 公开了一种由具有机械损伤如裂纹的检测结构的电绝缘材料制成的部件。 检测结构是导体。 检测结构的电性能随着越来越多的裂纹形成而被修改,使得部件在断裂之前将被及时更换。 电导体由彼此接触并具有金属表面的颗粒形成,使得产生对机械损伤特别敏感的电导体,从而使检测结构高度敏感。 此外,如果金属表面仅通过包覆颗粒而产生,同时颗粒的内部由与组分相同的材料制成,则对于受到大的热应力的组分,例如,具有适应的热膨胀特性的导体产生特征。 隔热板。
