Buckling of the reinforcing fibers is the primary deformation mechanism of such a new class of functional materials to realize a higher folding strain than that of conventional fiber reinforced composites. In this paper, the orientation of buckling direction of the reinforcing fibers in EMC laminate will be theoretically analyzed to better understand such deformation mechanism. The results reveal that the bucking protruding from the edge produces the lower energy needed for EMC laminate.展开更多

The equation to determine the buckling direction angle, beta say, was obtained and, as illustration, the solution curves of the equation for theta = 45degrees and theta = 30degrees were plotted. It is shown that when the fabric sheet is subjected to tension in non-warp/non-weft direction the out-of-plane buckling of fabric is possible, two buckling modes (flexural and extensional modes) and the both corresponding buckling conditions are obtained. The results given by ZHANG and FU (2001) are the special cases of this paper.展开更多
