TL;DR: In this article, an overview of the fiber surface modifications and newly developed techniques to promote fiber-polymer interfacial adhesion, focusing mainly on carbon fibers and glass fibers, is presented.
Abstract: Fibrous reinforcements are favored for advanced composites applications due to their excellent performance-to-weight ratio. Generally, the inorganic fibers surfaces are inert; hence, it is required to execute surface modification to enhance their wettability towards the matrix system. The weaker fiber–polymer interface caused intrinsically by hydrophobicity of reinforcing fibers as well as due to nonreactivity of matrix surfaces. This chapter is an overview of the research work carried out on the fiber surface modifications and newly developed techniques to promote fiber–polymer interfacial adhesion, focusing mainly on carbon fibers and glass fibers. The strengthening of nanostructured hierarchical surfaces and fiber–matrix interfaces/interphases is facilitating by fiber/matrix surface modification techniques, i.e., polymer sizings, chemical/dry treatments, and/or inclusion of various nano-additives at the composites interface. The investigations on the interface/interphase formation process and essential mechanism is analyzed by evaluating the mechanical properties of the nano-structured interface by advanced atomic force microscopic nano-mechanical and nano-tribological characterization. The stronger interface will be potentially applicable to composites health monitoring in various structural applications wherein the early disruption or mechanical failure is an essential criteria for performance enhancement.
