9.1 Advantages of using composite materials in blade manufacture
These benefits include
mass gain (figure 42 );
possibility of optimizing the material according to the mechanical constraints to be withstood (materials and their characteristics are developed at the same time as the part);
no corrosion (but beware of galvanic couples when in direct contact with other materials) ;
higher specific stiffness...
