COMPOSITE MATERIAL HAVING BIONIC STRUCTURE, METHOD OF PREPARING SAME, AND MODELING METHOD

摘要

A composite material having a bionic structure and a preparation method and a modeling method for the same are disclosed. A primary retinervus luffae fructus structure model is obtained by performing a modeling operation based on the mean values of the spatial structural characteristic values resulting from the statistics and analysis on spatial structural characteristic values of a retinervus luffae fructus, a finite element stress analysis is performed on the primary retinervus luffae fructus structure model, and a structural adjustment is performed on structural units according to the stressed nephogram of the primary retinervus luffae fructus structure model to obtain a retinervus luffae fructus structure model as the structure model of a composite material perform. A guiding device is created and a fiber winding order is determined based on the structure model, fibers are wound on the guiding device according to the determined fiber winding order to obtain a bionic retinervus luffae fructus structure as a composite material preform, and the obtained bionic retinervus luffae fructus structure is combined with a matrix to form the composite material. The composite material formed in a simulated manner is relatively high in tensile strength, high compression strength and high bending strength and effectively addresses the problem that the conventional composite material preform cannot be impregnated completely.
