Abstract

The concept of an interphase region between an adherent and a matrix or adhesive was first introduced in 1972 by Sharpe. Since this introduction, the role of the interphase region in controlling the performance of fibrous composites has been extensively investigated. Adhesion in the interphase region of fibrous composites is often ascribed to (1) mechanical interlocking, (2) physicochemical interactions, (3) chemical bonding, and (4) mechanical deformation of the fiber-matrix interphase region (Sharpe and Drzal). Provided item 4 does not change dramatically with interphase composition, a recent model by I. M. Ward suggests that fiber-matrix adhesion can be modeled as an additive sum of the first three factors. Self-assembled monolayer technology has been used to assess the contribution of these factors. Preliminary data indicates that adhesion in commercial interfaces is primarily due to mechanical interlocking and covalent bonding.
