Abstract
Recently as flat display panels are getting narrower, TV wall mounts also become slimmer for interior design issue. In this study CFRP(Carbon Fiber Reinforced Plastic) was used for TV wall mount to satisfy slim arm design along with enough strength and low weight. The 16 staking sequences was made with orthogonal array to reduce experimental cases. Strength analysis of the TV wall mount arm made of CFRP laminate was studied on condition of staking sequences using FEA(Finite Element Analysis) and stiffness and strength of those cases were evaluated using deflection and Tsai-Wu's Failure criterion. The result showed that [$-45^{\circ}/90^{\circ}/45^{\circ}/0^{\circ}/-45^{\circ}$] lay up case was suitable for the wall mount arm staking design from the criteria of deflection and Tsai-Wu's Failure Index.
