Factors affecting the effect of repairing damage of composite materials are mainly layer angle, angle and adhesive patch. This paper aims at different patching slope of composite laminates using ductile adhesives Araldite^@2015. The repaired specimens using bending mechanical properties and tensile mechanical properties were evaluated. The results show that the overlay[±45°]_4s laminates under bending load repair efficiency can reach the highest of 119.6%, under tensile load repair efficiency can reach the highest of 71.4%; layer[0°/90°]_4s laminates under bending load repair efficiency can reach the highest of 82.1%. These results can provide the basis and guidance for the actual repair.
