Structural analysis of coreless spoiler

Abstract

Abstract In this paper, a coreless spoiler is proposed to be an alternative solution for moisture absorbed honeycomb core. The honeycomb core is removed from the spoiler and the coreless spoiler is analyzed by using finite element tool, Abaqus. The results show that the upper skin fails at region near to the actuator, Tsai-Hill is more than 1. Few options, such as ßrib, spar and Carbon Fiber Reinforced Plastic (CFRP) patch are introduced to support the weak region of coreless spoiler. The effectiveness of these notions is evaluated based on Tsai-Hill failure. The spar outperformed the other options. Only the spar is capable of giving sufficient support to the coreless spoiler and the structure does not fail in term of Tsai-Hill index.
