Post Low Velocity Impact Vibration Response of Bio‐Composite Flax/Epoxy Plates: Validation of Experiment Setup.

Biocomposite materials are increasingly used in industrial transport structures (aerospace and automotive). They offer the ability to design complex parts, lightweight shapes that respond to high mechanical performance. Flax fibers are the most widely used because of their availability and mechanical properties, competitive to the properties of glass fibers. The detection of damage in these structures is essential to anticipate perilous consequences. Impacts induced damage is the most critical. The health control of a structure requires information about the severity and location of a damage through nondestructive methods. The aim of this study is to investigate vibratory behavior due to the impact on a biocomposite structure (flax/epoxy) to detect and evaluate the damage induced in noncontact method.
