[0026] The performance test of three different hole-filling glue resin ratio schemes is now carried out. The three different hole-filling glue resin ratio schemes are shown in Table 1. The ratio of resin, curing agent, and catalyst remains unchanged. The mechanical properties of hole-filling glue with different proportions are shown in Table 2, and the performance test results of hole-filling glue with different proportions are shown in Table 3.
