Abstract
Methods and systems for controlling a three(3)-dimensional distribution of structural reinforcement elements in a polymer-matrix composite. One embodiment of the invention provides a method that includes adding and curing a shape memory polymer in a plurality of flexible preforms attached with each other after preforming each of the flexible preforms to form a spatially controlled preform and variable stiffness material composite laminate. Here, in this embodiment, at least one of the preforms includes a flexible support formed from a patterned supporting material on a first surface of a stiff-structural sheet and the stiff-structural sheet that has been patterned on the support.
