Abstract: A system for structural health monitoring of a panel includes a panel of a composite laminate structure. The system further includes a plurality of sensors disposed on at least a surface of the panel each configured to measure at least an electrical datum associated with a portion of the panel. The system further includes a data acquisition system electrically coupled to the plurality of sensors and configured to receive the at least an electrical datum. The system further includes an alert system electrically coupled to at least the data acquisition system and configured to alert a user based on the at least an electrical datum.

Abstract: A system for a composite battery tray structure, the system including a floor extending in a longitudinal and transverse direction, the floor configured to receive at least one battery, at least one cross member disposed on the floor and extending in the transverse direction, the at least one cross member having a top surface, bottom surface and sidewalls extending vertically therbetween, the at least one cross member having a first flange extending vertically upward from the top surface, the at least one cross member having a second flange extending laterally from the bottom surface, the at least one cross member being hollow, with a support rib extending between the sidewalls and a lid disposed above the cross member, the lid having a channel extending upward, the channel configured to receive the first flange of the at least one cross member.
