Abstract
Composite materials have a wide field of applications in different types of industries such as automotive,
aeronautics, aerospace, transportation and military. Non-destructive evaluation, using ultrasound, plays an important role in the
prevention of catastrophic failures in engineering components and structures during their entire operational life. This work
presents the development of an experimental methodology for the generation, acquisition, processing, and interpretation of
ultrasonic signals in composite materials through the implementation of a signal acquisition, processing and storage interface
using the commercial software LabVIEW®. The use of the virtual instrument developed allows the monitoring and capture of
signals by implementing different filters during the inspection. Finally, an analysis of the captured signals is shown using the
Fast Fourier Transform, FFT, to determine the frequency components of the signal, implementing a function developed in
MATLAB®.
