Abstract

The invention discloses an adhesive shear strength test piece which comprises a bonding test piece A and a bonding test piece B. The bonding test piece A and the bonding test piece B are bonded in a lap joint mode through an adhesive, the bonding test piece A is located at the upper end of the bonding test piece B, and the center of the bonding test piece A and the center of the bonding test pieceB are located on the same straight line. The test piece has the advantages that the bonding test piece A and the bonding test piece B are positioned through the positioning holes in the two ends, themiddle place of 12.5 mm serves as bonding areas, after curing, only two adjacent strip-shaped hollow holes in the horizontal direction of the bonding test piece A need to be close to the bonding areas to be cut, and the bonding face does not need to be affected.

Description

technical field [0001] The invention relates to the technical field of material mechanical performance testing, in particular to an adhesive shear strength test piece and a manufacturing method thereof. Background technique [0002] The local overheating caused by the cutting process of the existing test plate after forming destroys the bonding interface, thereby affecting the test result of the shear strength. Contents of the invention [0003] The object of the present invention is to provide a kind of adhesive shear strength test piece and preparation method thereof, bonding test piece A and bonding test piece B pass two ends The positioning hole is positioned, and the middle 12.5mm is used as the bonding area. After curing, only two adjacent strip-shaped holes in the horizontal direction of the bonding test piece A need to be cut close to the bonding area without affecting the bonding surface. [0004] Technical scheme of the present invention is realized like this: ...
