Simulation for Microstructure Model of 3-dimensional Braided Composite Material
(0) This paper present a method to express the microstructure of 4-step 3-dimensional braided perform in mathematical way. Experimental investigation was employed to establish the relationship between braid structure and braid parameters. The equations of spatial configuration of trace yarn in each yarn group were obtained from the coordinates of center point of the trace yarn cross- section in perform and the microstructure of 3- dimensional braided perform was described in mathematical way. Based on microstructure of 3- dimensional braided composite, the whole structure of 3-dimensional braided composite perform was constructed when its different group, yarn configuration was set up in this way. Then resin volume of composite was formed after fiber percent of composite was determined. Compare with practical sample of 3-dimensional braided composite, the visual image of this model is feasible to be regarded as model of preprocessor of FEM.
