Three-dimensional (3D) integrated cellular woven structures are formed by binding layers of
typical 3D woven structures together in the thickness direction with binding threads.
According to 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
the orientation angle of the constituent yarns in each section within a unit cell were
calculated with the purpose of predicting the volume fraction of the fiber and the hollow part.
In order to verify the geometric model, 3D integrated cellular woven structure composites
with six various binding parameters were selected and the volume fractions of each part in
the composites were measured. Experimental results were in good agreement with the
calculated results of the model. Further, the geometric model was employed to discuss the
effects of the binding parameters on the volume fraction of the hollow part and the fiber
content. The investigation showed that the volume fractions of the hollow part and the fiber
content altered with the orientation angle of the warp.
