1. A method of manufacturing a bonding structural test block with defects, comprising the following steps:
providing a first plate (1) and a second plate (2);
applying an adhesive on an upper surface of the first plate (1) to form an adhesive layer (3);
heating and curing a plurality of preset region blocks (32) of the adhesive layer (3) for a first time, so that the plurality of preset region blocks (32) forms defects, wherein the plurality of preset region blocks (32) is distributed on the adhesive layer (3) at intervals;
placing the second plate (2) on the adhesive layer (3); and
heating and curing the adhesive layer (3) for a second time to form the bonding structural test block.
