Abstract

Repairing cracked parts using patches is a common method to restore mechanical properties and tensile strength. The efficiency of such patches can be achieved by obtaining the maximum amount of force borne by the repaired part and comparing it with the non-repaired part. The purpose of this study is to investigate the diffusion method used in the repair of cracked aluminum parts and to evaluate the patches and fibers used. In this study, the diffusion method is used to connect the aluminum patch to repair the central crack in the aluminum thin sheet. Examination of microstructures showed that using the diffusion method, parts can be welded together and a suitable part can be obtained without the use of glue. The process of repairing cracked parts made of aluminum or its alloys in this study involves the use of three types of patches and different fibers and different conditions, and finally pressing the patch and the piece together under heat for a certain period of time. The repaired parts are subjected to quasi-static tensile loading and the maximum amount of force borne by the part is obtained in different states.
