Axiomatic Design is a systematic design methodology with aid of matrixes that was developed by Nam Pyo Suh at MIT [4]. As long as, no research results related to the application of Axiomatic Design methodology to the Patch Repair have been found yet by the authors in the literature, some of methods of Composite Bonded Repair will be introduced and shortly reviewed here. Avram presented a process that comes from the Guidelines for Composite Repair to Metallic Structures handbook [5]. This process describes patch sizing using stiffness ratio and the analysis of critical area such as
patch tip stress, adhesive shear strain, peel stress, and stress intensity factor. Avram also gives some rules of thumb for patch and adhesive material selection and surface preparation.
