铝基复合材料是近年来发展起来的一类先进工程材料,具有高的比强度和比模量,特别是这些复合材料各向同性,并且具有比Be更高的抗微小变形的能力和优异的尺寸稳定性,另外,还可以对这些材料进行热膨胀系数设计以便和其他材料匹配。由于这些材料可以大批量、稳定制备,且可以精密加工成复杂形状,使它们成为惯性仪表构件的理想材料。本文综述了近年来,惯性领域中仪表级复合材料国内外的应用研究现状,讨论了仪表级复合材料应用对惯性仪表精度提高所产生的积极作用。
Aluminum matrix composites are a kind of advanced engineering materials developed in recent years. They have high specific strength and specific modulus, especially the isotropic properties of these composites, and have higher resistance to micro deformation than Be and excellent Dimensional stability, in addition, the coefficient of thermal expansion of these materials can also be designed to match with other materials. Because these materials can be mass-produced, stable, and can be precision machined into complex shapes, making them ideal for inertial instrumentation components. In this paper, the current status of the research on the application of instrument-level composite materials in inertial field in recent years is reviewed. The application of instrument-level composite materials to the improvement of inertial instrument accuracy is discussed.
