Elastic analysis of 3D woven orthogonal composite

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 z-fibers. 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.
