Abstract

In this paper, the influence of geometrical parameters on the compressive bearing capacity of the new repairable adaptive resin based carbon fibre composite single stiffener plate is analyzed by numerical simulation. The interface debonding and the progressive material damage are considered in the finite element model. For a single stiffener plate with a given layup sequence and basic dimensions, the structural optimization design can be carried out within a certain range. Due to the mismatch between the stiffness of the stiffener and skin, interface stress will increase, leading to early failure caused by interface damage. Considering and not considering interface failure will obtain different optimization results. The reasonable design of a single stiffener plate will directly affect the corresponding multi stiffened plate design.
