Abstract

The invention provides a manufacture method for a composite-material cementing structural test piece with a defect of air holes in a glue layer, and belongs to non-destructive detection field. The method realizes simulation of the air hole defect in the glue layer of the composite-material multi-layer cementing structure by employing 3D printing technology for preparing a glue-layer pad, and solves the technical problems that the size, shape, thickness and the like of an air hole defect in the glue layer cannot be quantitatively designed by employing the prior art. The method possesses the advantages of real and reliable simulation, high quantization precision, good expandability and the like.

Description

technical field [0001] The invention belongs to the field of non-destructive testing, and relates to a method for manufacturing a defect test block, in particular to a method for manufacturing a defect test block of a composite material bonding structure with air holes in the glue layer. Background technique [0002] Non-destructive testing technology uses the phenomenon that some physical properties of substances change due to defects or differences in organizational structure, and uses physical methods to measure these changes without destroying the performance, external shape and internal structure of the test object. It is a special detection technology to achieve the purpose of understanding and evaluating the nature, state, quality or internal structure of the detection object. At present, non-destructive testing technology has been widely used in machinery and equipment manufacturing, metallurgy, petrochemical industry, weapons, ships, aviation and aerospace, nuclear ...
