Digital-ray-direct-imaging interface morphology detection system for composite material and method

Abstract

The invention discloses a digital-ray-direct-imaging interface morphology detection system for a composite material and a method. The system comprises a detection chamber, a direct imaging device, cross rails and a processor, wherein the cross rails extend into an imaging area and are used for moving carrier loaders, and the processor is used for controlling the direct imaging device to automatically complete image acquisition and carrying out image processing on acquired images. The method comprises the steps: (1) mounting a composite plate, and feeding the composite plate to the imaging area; (2) determining a relative distance of an X-ray machine and an X-ray flat panel detector; (3) adjusting projection superposition of the X-ray flat panel detector and a ray radiation window of the X-ray machine; (4) controlling the X-ray machine and the X-ray flat panel detector to move synchronously, and carrying out digital-ray-direct-imaging detection on an interface of the composite plate; (5) carrying out image processing, and viewing corrugated morphology of an interface bonded area of the composite plate. According to the system and the method, digital-ray images of the interface of the composite plate can be acquired rapidly, clearly and visually, and corrugated morphologies of weak bonded areas of the interface of the composite plate are rapidly discriminated.

Description

technical field [0001] The invention belongs to the technical field of composite material interface topography detection, and in particular relates to a digital ray direct imaging composite material interface topography detection system and method. Background technique [0002] Metal composite materials have both the advantages of the matrix metal components, so that in addition to obtaining physical and chemical properties that a single metal does not have, it also saves a large amount of non-ferrous metals and rare metals. Layered metal composite material is a new type of metal composite material prepared by explosive compounding of any same or dissimilar metal, mainly including titanium / steel, titanium / stainless steel, copper / steel, zirconium / steel, tantalum / steel, Titanium / Nickel etc. At present, this composite material has been widely used in petrochemical, thermal power, nuclear power, aerospace and other fields. Layered metal composite materials, especially large-fo...
