Abstract
The invention relates to a device and a method for measuring bonding strength of a metal composite interface, a sample and a manufacturing method for the sample. The measuring device comprises an upper clamping pressing plate and a lower clamping pressing plate which are opposite to each other; the measuring device is characterized in that an upper groove and a lower groove penetrating the lengths of the upper clamping pressing plate and the lower clamping pressing plate are respectively formed on opposite surfaces of the upper clamping pressing plate and the lower clamping pressing plate; the upper groove and the lower groove are used for fixing and causing a measured sample pass through. According to the device provided by the invention, the upper and lower surfaces and the side walls of the measured sample are fixed between the pressing plates with grooves, so as to ensure the straightness of the measured sample in a stretching test process. According to the technical scheme provided by the invention, the traditional stretching shearing measurement method is used for quantitatively evaluating the bonding strength of the interface, the aluminum steel panel is prevented from being bent and deformed in the measurement process, the pulling force acting on the interface is kept on the same plane and the measurement result is relatively accurate.
Description
technical field [0001] The invention mainly relates to the measurement of the interfacial bonding strength of composite materials, in particular to a device and method for measuring the interfacial bonding strength of metal composite materials, a sample and a method for preparing the sample. Background technique [0002] The brazed aluminum-steel composite material is the main raw material for the base pipe of the air-cooling system of the thermal power station. The power station air-cooling system made of brazed aluminum-steel composite materials can save a lot of water resources and has significant economic and social benefits. Therefore, brazed aluminum-steel composite materials have become the metal layered structure composite materials that my country's "Twelfth Five-Year Plan" focuses on. One of the materials, the domestic development and application of this material is in its infancy. The aluminum-steel layered composite material for thermal power air cooling is made ...
