The assessment criteria for laser repair technology of composite materials mainly include the following three points: 1. Peeling off composite materials layer by layer. 2. Precisely controlling the size of the peeled-off area. 3. Ensuring the bonding performance of the epoxy resin under the exposed carbon fiber layer and preventing thermal effects.

The research approach for laser repair and shaping of composite materials involves the laser repair and shaping system acting on composite materials, followed by measuring various parameters of the composite materials before and after repair and shaping using various detection methods and instruments. After analysis and comparison, the technical advantages of laser repair and shaping of composite materials are summarized.
