Embodiment Construction

[0021] The present invention will be further described below in conjunction with the drawings and embodiments. Long thin-walled cylinder 5

[0022] Such as figure 1 As shown, a tooling for making an adhesive tensile and shear strength sample includes a base 1, a pressure system 2, and a cushion block 3.

[0023] Such as figure 2 As shown, the base 1 includes a bottom plate 4, a left groove 5, a right groove 6, a front pillar 7 and a rear pillar 8. The left groove 5 and the right groove 6 are symmetrically and vertically arranged on both sides of the surface of the bottom plate 4 to form a sample groove 9. The front post 7 and the rear post 8 are threaded for fixing the pressurizing system 2.

[0024] Such as image 3 As shown, the pressing system 2 is composed of a beam 10 and a pressing device 11.

[0025] Such as figure 1 As shown, the beam 10 is connected with the front column 7 and the rear column 8 by upper and lower nuts. The height of the beam can be adjusted by adjusting th...

Abstract

The invention relates to a production tooling for adhesive tensile shear strength test samples. The production tooling comprises a base, a pressurization system and a cushion block, wherein the base consists of a bottom plate, a left groove, a right groove, a left upright post and a rear upright post; the pressurization system consists of a beam and a pressurization device; the pressurization device consists of a pressurization plate, a reset spring and a pressurization threaded rod; the thicknesses of the cushion blocks are the sums of the substrate thicknesses and the adhesive layer thicknesses of the test samples. According to the production tooling, the overlapping length of the test samples can be accurately controlled; in addition, the parallelism and the coaxiality of the test samples can be ensured; moreover, multiple test samples can be prepared at one time according to a requirement.

Description

Technical field [0001] The invention relates to the field of mechanical properties of bonding between composite materials, in particular to a tooling for making adhesive tensile shear strength samples. Background technique [0002] Bonding has the advantages of no stress concentration caused by drilling, light connection structure, ability to maintain the continuity of composite fiber, fatigue resistance, etc., and has become the most important connection method for composite materials. Tensile shear strength is one of the important indexes for judging the bonding performance, so the tensile shear strength test is the most important method to evaluate the adhesive performance. [0003] At present, the commonly used sample preparation method is to manually apply the adhesive on the bonding area of ​​one substrate by the operator, then attach the bonding area of ​​the other substrate to the bonding area, visually measure the lap length, and finally use the tail clamp to clamp and add...
