Abstract
High strength and toughness seems like intrinsic conflicts in mechanical properties of materials, including composites interfaces. To solve this problem, we constructed a hierarchically structured interphase in aramid composites via in-situ grafting and foaming of polyurea on fiber surface and penetrating epoxy resin into the pores. As differential scanning calorimeter (DSC) and atomic force microscopic (AFM) confirmed, soft porous polyurea...
