Abstract

The paper presents the designing, technology, and characterising mechanical and damping properties of two types of structural components that might be useful in space applications. The components (struts) were produced by the gas pressure infiltration of molten Mg into a preform of continuous carbon fibres. For comparison, also a non-reinforced component from pure Mg was prepared. Vibroacoustic tests showed that the samples reinforced with carbon fibres had better damping – approximately two times higher loss factor (η = 0.0018 and η = 0.0021) than the cast Mg component (η = 0.0008). The bending tests confirmed the results obtained by vibroacoustic testing and revealed that the stiffness of the reinforced structural component was approximately six times higher than that of the unreinforced Mg material.

为空间应用设计和测试一个简单的结构部件

本文介绍了两种可能在空间应用中有用的结构部件的设计、技术和机械和阻尼特性。通过气体压力将熔融Mg渗透到连续碳纤维预制体中来生产组件(支板)。为了进行比较，还从纯Mg中制备了非增强组分。振动声学试验表明，碳纤维增强样品具有更好的阻尼-损耗因子(η = 0.0018和η = 0.0021)大约是铸态Mg组件(η = 0.0008)的两倍。弯曲试验证实了振动声试验的结果，表明增强后结构构件的刚度比未增强的Mg材料高约6倍。主要应用领域:金属基复合材料、镁基复合材料、碳纤维、气体压力渗透、空间应用

期刊介绍： Kovove Materialy - Metallic Materials is dedicated to publishing original theoretical and experimental papers concerned with structural, nanostructured, and functional metallic and selected non-metallic materials. Emphasis is placed on those aspects of the science of materials that address: the relationship between the microstructure of materials and their properties, including mechanical, electrical, magnetic and chemical properties; the relationship between the microstructure of materials and the thermodynamics, kinetics and mechanisms of processes; the synthesis and processing of materials, with emphasis on microstructural mechanisms and control; advances in the characterization of the microstructure and properties of materials with experiments and models which help in understanding the properties of materials.
