Mechanical properties of structure-energy storage integrated composites

In order to explore the single-point stress damage form of structure-integrated composite battery panels, the mechanical properties of structure-energy storage-integrated composite battery panels are simulated. In this paper, starting from the laminated structure of composite panels, through the strength and stiffness simulation of panels with different layup programs, it can be found that the strain changes of different layup programs basically satisfy the symmetric distribution form of layer-by-layer decreasing, and the difference lies in the strain expansion form of the fixed end and the external loading place. The maximum deformations of the different layup schemes all occurred at the distal non-fixed end, and the deformations gradually increased from the fixed end to the distal end with good layup and symmetry. Therefore, for the mechanical properties of composite panels, the best performance is achieved when 90° carbon fibers are the main body of the layup, the second best performance is achieved when 45° carbon fibers are interspersed with positive and negative rows, and the worst performance is achieved when 45° carbon fibers are the main body of the layup angle.
