Abstract:

Following the geometric pattern of the constituent yarn system in 3D integrated cellular woven structures, a general purpose geometric cell model was developed. The length and orientation angle of the constituent yarns in each system within a unit cell were calculated with the purpose of predicting the volume fraction of the fiber and the cellular part. In order to verify the geometric model, samples of 3D integrated cellular woven composites with 6 different binding parameters were selected, and the volume fractions of each part in the composites were measured. The experimental results were in good agreement with the results of the model. Furthermore, the geometric model was used to discuss the effects of the binding parameters on the volume fraction of the cellular part and the fiber. The investigation showed that the volume fractions of the cellular part and the fiber varied with the binding length of section E.
