Detection of Damage in CFRP Lamina by Static and Dynamic Tests
Recently, the monitoring of FRP elements through damage detection has become one of the most important aspects of the use of Fiber-Reinforced Polymers (FRPs) in civil engineering, both in the rehabilitation of existing structures and in the construction of new ones. Non-destructive methods based on experimental vibration monitoring can adequately perform this task. FRP structures change their dynamics due to actual damage from defects, loss of integrity, and cracking of the FRP material due to overloading during service or damage. The response of Carbon-FRP lamina to vibration with damage has been studied experimentally, considering as damage variation pf frequency values due to tensile tests up to 80% of strength. Below are the changes in natural frequency values obtained from dynamic tests that are related to the degree of damage to CFRP laminas. A numerical model has been developed for a theoretical study of damaged CFRP laminas under vibration. The theoretical frequency values are compared with those obtained from experimental tests.
