Problems solved by technology

T-peel is an important method to test the interface bonding performance. In order to obtain the same force in different directions, two material testing tensile machines (referred to as tensile machines) are usually used for testing, which is very cumbersome and expensive.

Abstract

The invention discloses a peeling testing device and a testing method thereof. The peeling testing device comprises a bottom plate, wherein a guide track is mounted on the bottom plate; a moving plate is connected with the guide track; a tension column of a tension machine is arranged above the bottom plate; a connecting base is mounted at the top of the tension column; the connecting base is connected with a connecting plate; a coiling disc is mounted at the other end of the connecting plate; one end of a guide wire is connected with the coiling disc; the other end of the guide wire is connected with the moving plate; a clamp is arranged below the tension column; a pressing plate is arranged on the moving plate. By adopting the peeling testing device, overall peeling force is always conducted in an axis position of a test part, the moving plate is moved forwards at a uniform velocity same as that of the tension column while the test part is peeled along with the action force, then the T-shaped peeling testing process is achieved, T-shaped peeling is accurately achieved, and the interface bonding properties are effectively detected; the peeling testing device is simple in structure, good in practicability and easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of mechanical performance testing, and in particular relates to a wing plate lifting device. Background technique [0002] The good bonding of solid rocket motor casing / insulation layer / lining layer / propellant interface is the key to ensure the structural integrity of the motor charge, which is directly related to product safety, reliability and service life. Due to the different load directions of the bonding system at the head, middle and tail of the engine, when the engine is stored, transported, hoisted, and ignited, the direction of the loads borne by the various ministries of the bonding system will also change, causing the bonding system to bear Tensile, shear, and mixed stress states, it is therefore necessary to test the mechanical properties of the bonded system under various loaded states. T-peel is an important method for testing the interface bonding performance. In order to obtain the same for...
