Elastic Analysis of 3D Woven Orthogonal Composite

摘要：

This paper proposes a methodology to predict the engineering elastic constants of 3D woven orthogonal composites based on volume averaging method.For accurate predictions, emphasis is given to accurate measurements of micro-structural data, such as fiber volume fraction, fiber volume proportion of constituent tows, and internal geometry of the composite structure-especially undulation of zfibers.Microscopic study has been conducted in this regard.The predicted engineering elastic constants are compared against experimental data, showing a strong correlation between predicted and experimental values.
