A test method for interlaminar toughened thick CFRP laminates in the out-of-plane direction was studied. Unidirectional thick CFRP laminates whose thickness is approximately 17 mm were used in this study. Spool specimens machined from that thick laminates were loaded in the out-of-plane direction. Metal tabs were bonded to upper - and - lower surfaces of a specimen. At the bonding process, an alignment fixture was used to enhance alignment precision. In addition, an axis adjuster using wood's metal was used to connect the specimen with a testing machine with high axial precision during the tests. As a result of static test, it was confirmed that tensile and compressive load were applied without bending deformation. As a result of fatigue test, it was confirmed that the fatigue life at stress ratio of R=-1 is shorter than that at R=0.1.
