Abstract

Composite structures are widely used in the aviation, automotive industries nowadays. This is because of its corrosion resistance, lightweight, and endurance. Carbon fiber reinforced polymer (CFRP) could be seen even in present-day highend bikes. Even though they are widely used and have a lot of pros, they are prone to various damages and most importantly the impact damage. These impact damages may occur due to accidental drop, low impact drop of tools during testing, etc. This could lead to damage to the material structure, its matrix, fibers, etc. This reduces its entire strength. In our studies, we have focused on the experimental and numerical analysis of the impact damage (ID) detection on multilayered CFRP material using Lamb waves. Lamb waves or guided waves are widely used in various damage detection techniques in the present structural engineering world. The experimental study was performed using a laser Doppler vibrometer (LDV) with piezo zirconate titanate (PZT) based Lamb wave excitation to detect the damage locations. This is followed by signal processing tools to visualize it. The numerical study was conducted using a spectral elemental method (SEM). The results from the experimental, numerical studies revealed the location of damage zones in the CFRP plate.
