Abstract
The present disclosure provides a method of manufacturing a bonding structural test block with defects. The method of manufacturing the bonding structural test block with defects includes: providing a first plate and a second plate; applying an adhesive on an upper surface of the first plate to form an adhesive layer; heating and curing at least partial region of the adhesive layer for the first time; placing the second plate on the adhesive layer; and heating and curing the adhesive layer for the second time to form a boding structural test block. According to the present disclosure, the at least partial region of the adhesive layer is heated and cured for the first time and chemical reaction occurs, so that the at least partial region forms a defect, and controllable manufacturing of the defect is realized. The test block with the defect is subjected to mechanical detection to simulate the actual defective product. Furthermore, according to the method provided by the present disclosure, weak bond defect and kiss-bonds defect with different bonding strength are simulated by controlling the percentage of the at least partial region in the entire region of the adhesive layer.
