Problems solved by technology

Because it is a manual operation, it is difficult to control whether the two laminates are parallel and symmetrical and whether the thickness of the adhesive layer is uniform. raised higher demands
The above situation caused the sample to be abnormally damaged during the test process, resulting in low test results and large dispersion
At present, there is a lack of suitable sample preparation methods and tooling

Abstract

A tensile and shear sample preparation tool with controllable adhesive thickness, including a bottom plate, two side plates and a horizontal support plate, each side plate is vertically provided with a pair of parallel groove channels, and one side of the groove channel is provided with Scale, the same scale on the two side plates is at the same level, and the fastening device matched with the groove channel includes a pair of bolts, metal blocks and nuts, the head of the bolt is matched with the groove channel, and clamped In the groove channel, the threaded part of the bolt passes through the metal block and is connected with the nut. The horizontal support plate is fixedly connected with the metal block. One of the side plates is provided with a horizontal pressure plate above the horizontal support plate, and the horizontal pressure plate is horizontal below the horizontal support plate. The projection on the support plate covers the overlapping bonding area of ​​the laminate on the two horizontal support plates. The invention can accurately control the thickness and uniformity of the adhesive layer in the sample preparation process, obtain a specific required thickness, and conveniently completely clean up the excess adhesive extruded.

Description

technical field [0001] The invention belongs to the technical field of sample preparation methods and devices, and mainly relates to a tensile shear sample preparation tool with controllable adhesive thickness. Background technique [0002] The tensile and shear properties of laminates and laminates are one of the important indicators for investigating and selecting structural adhesives for wind turbine blades. The tensile and shear properties are mainly reflected by the tensile shear strength. The mechanical properties of the adhesive directly reflect the load-bearing conditions of all aspects after the adhesive is bonded to the blade, and how to accurately prepare samples before the test is seriously related to the accuracy and discreteness of the test results. The current standard mainly stipulates the control method for the thickness of the adhesive layer to be 0.2mm, and the commonly used sample preparation method is to apply the adhesive on one end of a laminated board...
