Vibro‐acoustic analysis of a post‐impacted woven composite panel

In this study, vibro‐acoustic behavior of centrally damaged woven carbon composite panels is investigated experimentally. For this purpose, evaluations are considered by the followings: (i) ballistic impact measurements are completed regarding with two different shooting distance, (ii) ballistic impact measurements with three different projectiles are obtained, (iii) vibration and vibro‐acoustic tests are performed to present the vibration characteristics of the post‐impacted woven composite panels. Effects of shooting distance and projectile on modal and sound characteristics are examined. Results are given in tabular and graphical forms. By using an acoustics demonstrator, this study describes to determine the vibro‐acoustic behavior of damaged woven composite panels as a function of basic parameters, such as shooting distance (5 or 25 m) and type of projectile (MKEK Parabellum, Remington Luger or Remington UMC).
