Self inspection and acceptance criteria for CFRP strengthening are listed in the table below

• When the bonding quality is not required, the carbon fiber fabric should be cut off along the edge of the empty drum. The size of 100mm is extended to the outer edge of the same carbon fiber material, and the same binder is used in the original.

• When the strength fails to meet the requirements, the carbon fiber composite material represented by the sample inspection shall be stripped and redone.

• The self inspection method of CFRP strengthening is visual inspection or percussion. Inspection standard: the surface of the reinforcement should be strengthened without any glue, gaps, dry yarn, wrinkles, bubbles and sunken defects. Detection time: 3-5 days after completion, check the area with visual or metal mallet (small).
