Fiber-reinforced composites (FRPs) find extensive applications in aerospace, wind turbine blades as well as prosthetics. A combination of high strength and stiffness while having relatively less density is the primary reason for this. However, they are prone to delamination under bending and compressive stresses. This is due to poor nature of interface between the fiber and the matrix. Our lab works on improving the interphase/interface between the fiber and the matrix using nano-fillers deposition on fibers. Such techniques have been found to enhance the mechanical properties significantly.
