ABSTRACT

This chapter intricately examines the mechanical interactions occurring at the interface between fiber and matrix in carbon-fiber-reinforced plastics (CFRPs). By delving into the mechanics of these interfaces, it elucidates the interplay of normal and shear stresses. The distinct roles of interfacial strength and its evaluation are explored, culminating in the conceptualization of failure envelopes on the normal stress–shear stress plane. Notably, the interface strength’s independence from time and temperature is substantiated. Through a meticulously crafted journey, this chapter lays the groundwork for a profound understanding of the interface mechanics that shape the durability of CFRP.
