Evaluation of elastic properties of 3-D (4-step) regular braided composites by a homogenisation method

In this article a homogenisation method that considers the internal interface condition of a heterogeneous medium is established. The relevant formulae are developed based on a specific stratified medium with plane interfaces, but they can be obtained for more general cases in which curved interface...

Zusammenfassung:	In this article a homogenisation method that considers the internal interface condition of a heterogeneous medium is established. The relevant formulae are developed based on a specific stratified medium with plane interfaces, but they can be obtained for more general cases in which curved interfaces are considered. A 3-D 4-step regular braid is studied, and its elastic properties are evaluated in terms of the homogenisation scheme. The present theoretical prediction shows a good agreement with experimental data.
