 note = {This paper presents the results of tests conducted on the static bending strength and flexural fatigue strength of a honeycomb sandwich beam comprising an aluminum honeycomb core and graphite fiber reinforced plastic facings. The static bending strength was measured by a Shimadzu AUTOGRAPH IS-20T Instrontype testing machine, and the low cycle flexural fatigue strength was by an AUTOGRAPH IS-20T and Shimadzu SERVOPET Lab-5 electro-hydraulic testing machine. In the flexural fatigue test, conducted under a fluctuating bending stress of “R=0.1”, a piece of rubber plate of 35mm in length, 30mm in width, and 3mm in thickness was attached at each loading point on the CFRP aluminum honeycomb sandwich beams in order to prevent undesirable damage due to the concentrated loading. It was found that the static bending strength as well as flexural fatigue strength of the honeycomb sandwich beams depended mainly on the properties of the facing materials. It was also found that the CFRP aluminum honeycomb sandwich possessed sufficiently high strength, both static bending and flexural fatigue, for employment as a structure component., 資料番号: NALTR0456000, レポート番号: NAL TR-456},
