Abstract: In composites the role of the interface is crucial. Stiffening and strengthening rely on load transfer across the interface, toughness is influenced by crack deflection/fibre pull-out, and ductility is affected by relaxation of peak stresses near the interface. Unfortunately, however, a great deal of confusion surrounds the question of how best to characterise, and then optimise, the mechanical response of the interface to stresses arising from an applied load. In this chapter, a brief outline is given of the meaning and significance of interfacial bond strength, followed by a summary of the methods used to measure interfacial mechanical properties, with particular reference to fibrous MMCs. Some attention is then devoted to interfacial chemical reactions. Finally, the production and characteristics of fibre coatings are briefly examined.
