Abstract

In the past, the fiber bundles were mostly meshed for computing the mechanical properties of the unit cell in fabric composites. Consequently, not only the degrees of freedom but also the complexities in computation are increased. To improve the efficiency in analysis, in this study, a previously developed spring model was extended to predict the effective elastic moduli of three-dimensional (four-step) braided tubes. In the meanwhile, a related compression test was conducted to validate the computational results. It is shown that the results from the computation agree well with the experimental results. In addition, the effects of fabric parameters (such as surface braid angle and fiber volume fraction in a fan-shaped unit cell) on the effective elastic moduli of three-dimensional (four-step) braided tubes were also investigated.
