PROBLEM TO BE SOLVED: To provide a system and method for measuring stress in a composite structure having an integrated sensor network.SOLUTION: A composite structure is formed in layers, each being formed from parallel fibers. At least one of the layers includes a plurality of fiber sensor cells distributed among the parallel fibers, each fiber sensor cell 100 having an inner fiber core 110 and a non-conductive layer 120 formed to cover the inner fiber core 110. A controller is electrically coupled to each fiber sensor cell 100 and configured to determine a level of stress in the composite structure on the basis of change in resistance level of the inner fiber core 110 of each fiber sensor cell 100. The fiber sensor cells may be in a single direction or in a weave pattern comprising a first group arranged at a non-zero angle with respect to a second group.SELECTED DRAWING: Figure 1
