诺梅克斯材料和诺梅克斯蜂窝结构的力学特性

Mechanical Properties of Nomex Material and Nomex Honeycomb Structure

介绍了对诺梅克斯纸和诺梅克斯蜂窝的线弹性力学特性的大量测试结果。诺梅克斯纸的基本力学特性被应用于有限元模型和诺梅克斯蜂窝结构分析。有限元计算结果与试验结果以及人们熟知的Gibson和Ashby公式计算结果进行对比,观测了诺梅克斯蜂窝模数的尺寸效应。

This paper presents extensive test results of linear elastic mechanical properties of Nomex paper and Nomex honeycomb structures. The fundamental mechanical properties of the Nomex paper are then used in the finite element modeling and analysis of Nomex honeycomb structures. The finite element results are then compared with the experimental results and with the results using the well known theory from Gibson and Ashby [Gibson L J, Ashby MF. Cellular solids： structures ＆ properties. Pergamon Press; 1988]. Size effects are observed for the moduli of Nomex honeycombs.
