AI Technical Summary
Existing composite material repair methods suffer from low repair strength, complex processes, high energy consumption, low recovery rate of mechanical properties after repair, making it difficult to meet high reliability requirements, and poor feasibility of on-site repair.
The repair is achieved by using a core-pulling assembly, which includes a polyethylene core-pulling rod, wet prepreg, and a nut. The repair is accomplished by drilling holes in the damaged area of the composite material and curing it, and then connecting the nut with a threaded connection.
It achieves high-strength repair, enhances structural load-bearing capacity, has a simple repair process, high repair strength, and a firm connection between the repair layer and the base structure, making it suitable for repairing complex structures.
