A study on the FRP composite’s matrix damage resistance by means of elastic wave propagation analysis

Damage Pattern Recognition for Corroded Beams Strengthened by Cfrp Anchorage System Based on Acoustic Emission Techniques

“…Since the FRP composite structure is a combination of FRP sheet, FRP anchors and reinforced concrete, its force characteristics and damage mechanism are more intricate than for RC structures [18][19][20]. To completely clarify the damage mechanism of FRP composite structures, all damage mechanism, such as matrix cracking, the fiber-matrix debonding, the fiber breakage, must be elucidated, which poses a challenge to the analysis of the damage mechanism of FRP composite structures.…”
