摘要： Method and system are disclosed for characterizing and quantifying composite laminate structures. The method and system take a composite laminate of unknown ply stack composition and sequence and determine various information about the individual plies, such as ply stack, orientation, microstructure, and type. The method and system distinguishes between weave types that exhibit similar planar stiffness behaviors, but which produce different failure mechanisms. Individual ply information then is used to derive the laminate bulk properties from externally provided constitutive properties of the fiber and matrix, including extensional stiffness, bending-extension coupling stiffness, bending stiffness, and the like. The laminate bulk properties are then used to generate a probabilistic failure envelope for the composite laminate. This provides the ability to perform non-destructive QA to ensure that individual lamina layup was accomplished according to specifications, and results are used to identify numerous laminate properties beyond purely structural ones.

摘要： Embodiments are disclosed for characterizing and quantifying composite laminate structures. The embodiments take a composite laminate of unknown ply stack composition and sequence and determine various information about the individual plies, such as ply stack, orientation, microstructure, and type. The embodiments distinguish between weave types that exhibit similar planar stiffness behaviors, but produce different failure mechanisms. Individual ply information is then used to derive the laminate bulk properties from externally provided constitutive properties of the fiber and matrix, including extensional stiffness, bending-extension coupling stiffness, bending stiffness, and the like. The laminate bulk properties are then used to generate a probabilistic failure envelope for the composite laminate. In some embodiments, ply stack type and sequence are also determined for a curved composite laminate using the disclosed embodiments by adding a rotational stage.

摘要： A sensor array housing device includes an enclosed couplant housing section between a linear array of transducers or coils and a test object. The linear array is particularly suited for sectoral scanning of a test object. Interior surfaces of the couplant housing section include a plurality of ridges for mitigating the impact of reflected side lobes on scan data. The sensor array housing device includes a plurality of retained articulating balls, configured to allow the sensor array housing device to move omnidirectionally across a surface of the test object.

摘要： An apparatus for scanning a cylindrical part is provided. The apparatus includes an ultrasonic transducer operable to emit ultrasonic waves into and receive ultrasonic waves from the part, with the ultrasonic transducer connected to a translation stage to move it up and down the part and around the circumference of the part. The apparatus does not mechanically contact the cylindrical or maintains contact only with soft elements, such that the apparatus does not damage sensitive parts. The apparatus also contains no magnetic parts, nor any elements that rely on magnetic detection, such that the apparatus is capable of being used in the vicinity of a part exhibiting a strong magnetic field.

摘要： The present disclosure provides a system and method for real-time visualization of a material during ultrasonic non-destructive testing. The system includes a graphical user interface (GUI) capable of showing a three-dimensional (3-D) image of a composite laminate constructed of a series of two-dimensional (2-D) cross sections. The GUI is capable of displaying the 3-D image as each additional 2-D cross section is scanned by an ultrasonic testing apparatus in real time or near real time, including probable defect regions that contain a flaw such as an air pocket, delamination, or foreign object within the composite. Furthermore, in one embodiment, the system includes an artificial intelligence capable of highlighting foreign objects within the 3-D image in real time or near real time and providing data regarding each object area, such as the depth, size, and/or type of each defect.

摘要： The present invention is directed to nondestructive testing of objects, and more specifically to a system for nondestructive testing of an object using a robotic arm. The end effector of the robotic arm is equipped with an arrangement of paired, angled transducers and an orthogonal transducer configured to scan an object using multiple wavelengths of ultrasonic sound waves. Multiple scans of a test object are taken as the object is rotated and the scans are then wirelessly transmitted to a user device or a remote server.
