METHOD FOR PREPARING BONDED JOINT SPECIMEN, BONDED JOINT SPECIMEN, AND TESTING METHOD FOR TENSILE BOND STRENGTH

摘要

PROBLEM TO BE SOLVED: To provide a method for preparing a bonded joint specimen, in which such the bonded joint specimen can be prepared that imbalance of a bonded state hardly exists between the central vicinity of the bonded plane and the edge vicinity thereof, and to provide the bonded joint specimen and a testing method for tensile bond strength.;SOLUTION: When one adherend 1 and the other adherend 4 are bonded to each other by using an adhesive 3 to prepare the bonded joint specimen, the area of an adhesive plane 4a of the other adherend 4 is set larger than that of another adhesive plane 1a of the one adherend 1 and the adhesive 3 is applied to the space between the adhesive plane 1a of the one adherend 1 and the 4a of the other adherend 4 so that an excess portion 3a of the adhesive 3 is brought into contact with the side face 1b existing along the edge of the adhesive plane 1a of the one adherend 1 having the adhesive plane 1a of the smaller area.;COPYRIGHT: (C)2015,JPO&INPIT
