Introduction Cold Spray or Supersonic particle Deposition (SPD) is a coating technology was initially developed in the mid-1980s at the Institute for Theoretical and Applied Mechanics of the Siberian Division of the Russian Academy of Science in Novosibirsk [1].Cold spray is a technology in which metal, composite or polymer powder particles in a supersonic jet of compressed gas impact a solid surface with sufficient energy to cause plastic deformation and bonding with the underlying material without the creation of heat affected zones which are typical of other deposition processes (thermal spray) and which are undesirable in many structural applications [1].
Rotor blades are made out of various materials, including aluminum, composite structure and steel or titanium with abrasion shields along the leading edge.
For propeller blade repair, if using doubler method, doubler of the same type material must be used and one gauge thicker than the surface to be repaired.

With numeric simulation technology in different conditions such as different thickness and different strength combination of TWB’s materials, the forming limit depth (FLD) of tailor welded blanks is analyzed.
The simulation result indicates that, when use different material and thickness blank for welding, the deformation of TWB depends on strength ratio and thickness ratio of two kinds of materials.

This demonstrates the complexity of the design of concrete structures with FRP reinforcement, also emphasizes the need to understand behavior of both materials as structural system.
Compatibility is considered as a basic rule for selection of materials for repair of concrete structure.
