| Abstract: | The micro-geometry-structure of a 3D woven composites is studied. The difference between the outer and the inner weft is analyzed by adopting the assumption of ellipse fibers. A new mechanical model for the 3D woven composites is established to predict engineering elastic constants. Molding method for the 3D woven composites is also studied. Experimental samples are made and experiments are performed to determine the mechanical properties. Theoretical predictions agree well with the expe-rimental results, thus the proposed model is verified. |
