고기능성 복합신소재를 이용한 허니컴 샌드위치 패널의 최적설계

Abstract

A typical honeycomb sandwich panel consists of two thin, high-strength facings bonded to a thick, light-weight core. Each component by itself is relatively weak and flexible, but when it combined in a sandwich panel they produce a structure that is stiff, strong, and lightweight. In addition to use in honeycomb sandwich panels, honeycomb is used for energy absorption, radio frequency shielding, light diffusion, and to direct air flow. Accordingly, the usage of honeycomb sandwich structure is very widely applied to the aircraft, the automobile, and marine industry, etc., because of these advantages.

With the increasing interest in using the sandwich structure with honeycomb core, there is also an increasing demand for knowledge and basic understanding of the processing technology for these relatively new materials.

Generally, this honeycomb sandwich structure is manufactured by autoclave process. In this study, the honeycomb sandwich structure was produced by prepreg. To prove the suitability the honeycomb sandwich structure with prepreg. The optimum design of the skin materials and honeycomb sandwich structure were evaluated with the theory of stress analysis.

In the study, a pallet having a thickness about 25 mm, applied to produce LCD/PDP, using honeycomb sandwich panel is designed by optimism from stress analysis of composite material. And it can get the following conclusion.

The result of designing a pallet manufactured by honeycomb sandwich having a thickness, 20mm, it is satisfied against the standard, so it makes sure that designing a pallet is optimized.
