The relationship between the laminated angle of CFRP and fracture strength under pure bending was also investigated. The method of analysing the fracrure strength of laminated CFRP was as follows: the three-dimensional stress components referring to the plane including fiber were analysed, taking into account elastic failure prior to overall fracture, then comparing this with the fundamental strength corresponding to the afore-mentioned kind of fracture mechanisms of unidirectional fiber reinforced composites. Laminated CFRP aluminum honeycomb sandwich beams make use of facing laminated angles of ±45 deg/minus/plus45 deg, 90 deg/±25 deg/0 deg, 25 deg/90 deg/0 deg/-25 deg and 45 deg/90 deg/0 deg/-45 deg. In the static bending test, pieces of 5mm-thickness rubber plate and 2mm-thickness aluminum plate were attached at each loading point on the laminated CFRP aluminum honeycomb sandwich beams in order to prevent undesirable damage due to concentrated loading. It was found that fracture strength and fracture modes obtained in the CFRP aluminum honeycomb sandwich beams bending fracture test of laminated CFRP have a good correspondence with taht of analysis., 資料番号: NALTR0527000, レポート番号: NAL TR-527}, title = {積層CFRPハニカムサンドイッチ材の強度}, year = {1978} }
