A nature-inspired interface design strategy of carbon fiber composites by growing brick-and-mortar structure on carbon fiber

Poor interfacial interaction and damage-tolerance restrict practical application of carbon fiber (CF) composites. The brick-and-mortar structure meets the requirements of high strength and small crack growth behavior of composites. However, uniformly fabricating the three-dimension brick-and-mortar structure as an interface layer on CF surface remains a challenge. To fill up this technical gap, herein, 3D brick-and-mortar structures were...
