Verifiable quick patch repair for composite structures

A composite structure comprising:

• a parent structure having a hole, said parent structure being made of composite material;
• an insert in said hole, said insert being made of composite material;
• a first patch bonded by adhesive to one side of said parent structure and one side of said insert, said first patch being made of composite material, wherein said first patch comprises a central portion and a first multiplicity of pre-stressed members that extend outwardly from an outermost portion of said central portion of said first patch and are separated by slits, wherein said central portion of said first patch is directly bonded to said one side of said insert by adhesive therebetween, and each of said first multiplicity of pre-stressed members is directly bonded to opposing portions of said one side of said parent structure by adhesive therebetween and has the property that at least a portion of the pre-stressed member will deform toward an unflexed state in the event that a bond strength between said portion of said pre-stressed member of said first multiplicity and an opposing portion of said one side of said parent structure changes from a non-zero value to zero;
• and
• a second patch bonded by adhesive to another side of said parent structure and another side of said insert, said second patch being made of composite material, wherein said second patch comprises a central portion and a second multiplicity of pre-stressed members that extend outwardly from an outermost portion of said central portion of said first patch and are separated by slits.
