Problems solved by technology
It is difficult to meet the test requirements with a simple mold, and often the adhesive will bond the sample to the inner cavity of the mold, resulting in the tensile test being unable to release the mold, and the mold can only be mechanically destroyed, resulting in test failure

Abstract
A sample adhering and stretching mold and a sample adhering and stretching method are provided. The mold comprises a sleeve device and a rotating device. The sleeve device comprises a sleeve used for accommodating a sample to be adhered, a sleeve clamping rack used for fixing the sleeve, and clamping screws used for clamping the sleeve. The rotating device comprises a rotating arm fixed to the sleeve clamping rack, a rotating sleeve tube fixed to the other end of the rotating arm and fixedly mounted at the inner center axis of a tube base, the tube base used for a locking device to rotate, and the locking device comprising a hand shank and a locking bar, wherein one end of the locking bar is fixedly connected to the rotating sleeve tube and the other end of the locking bar is connected to the hand shank, and the rotating sleeve tube can be rotated by 0-90 degrees by rotating the hand shank. By the structure design, coaxiality of parts of the sample after adhesion can be ensured, the sample is prevented from being adhered to the inner cavity of the mold with an adhesive, and testing reliability is improved.
Description
technical field [0001] The invention mainly relates to the technical field of interface bonding of composite materials, in particular to sample bonding, stretching molds and sample bonding and stretching methods of aluminum-steel composite materials. Background technique [0002] Metal layered composites can obtain excellent comprehensive properties because they can utilize the respective advantages of the component layer metals. At present, metal layered composite materials have been more and more widely used in aviation, aerospace, petroleum, chemical industry, automobile, construction and other fields. The interface bonding strength of this type of material is limited by material characteristics, production process and other conditions, and there may be poor or no bonding, which will affect the use effect of the product and even shorten the service life of the product. [0003] Therefore, the bonding quality of the metal interface has been used as the main index to evalu...
