Abstract: 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 a hole, crack, wrinkle, or foreign object within the composite. Furthermore, in one embodiment, the system includes an artificial intelligence capable of highlighting defect areas within the 3-D image in real time or near real time and providing data regarding each defect area, such as the depth, size, and/or type of each defect.

Abstract: The disclosure provides a system and method for ultrasonic non-destructive testing to monitor the curing process of a resin and filled resin materials during manufacture. The inventors have discovered that ultrasound parameters revealed in ultrasonic signal analysis reveals the degree of cure and therefore important curing stages during processing for a proper cure and allow the product to perform as intended. Generally, the ultrasound parameters include signal speed of sound and/or instantaneous peak power relative to wall-clock time of the ultrasound signal. The system and method can monitor the cure of resin and filled resin materials using instantaneous data without the need for previous data for that individual scan, can use ultrasound portably such that carbon fiber laminates can be monitored in-situ, and is conducive to isothermal cure or cure using a varying temperature profile. Thus, the invention represents a step in manufacturing of resin-curing products heretofore unavailable.

Abstract: A method for ultrasonic inspection of fused filament fabrication (FFF) manufactured samples and of carbon fiber reinforced polymer (CFRP) laminates is disclosed that includes performing a time-frequency transforms including the short-time Fourier transform (STFT) and the wavelet synchrosqueezed transform (WSST), inspecting features in FFF manufactured samples for porosity, layer height and missing extrudate and visualizing CFRP laminate wrinkle.
