“…Thus the increase in ISS is probably due to the increase in modulus as predicted by the shear lag model and supported by Asloun et al (27). In addition, they found that the modulus of an amine depleted region with 7.5 phr was 1.5 times the modulus of a cured resin with 14.5 phr (stoichiometric ratio).…”

The propagation of damage in continuous fiber polymer matrix composites depends strongly on the fiber / matrix interface (interphase). Therefore it is critical to measure interface behavior. The recent application of micro-Raman spectroscopy (MRS) in the field of composites micromechanics has created a new era of experimental micromechanics and shed light on a number of crucial points. MRS, with the ability to measure local stresses with a spatial resolution of 2 pm, allows very close monitoring of the interfacial behavior in composites including interfacial crack initiation and propagation. This paper will demonstrate the application of MRS on monitoring and understanding the effect of an interphase on the composite interfacial micromechanics. Namely, the effect of fiber sizing on the composite micromechanics will be presented and compared to micromechanical models and to results obtained using other interfacial measurements techniques. The properties of the created interphase, due to fiber sizing, and its relationship to the fiber volume fraction of the composites are also discussed.

“…When the yield stress is assumed to be constant, the critical fiber length l c based on the shear lag theory could be related to the fiber and matrix properties, as was derived by Galiotis et al [50] and Asloun et al [51]: When the yield stress is assumed to be constant, the critical fiber length l c based on the shear lag theory could be related to the fiber and matrix properties, as was derived by Galiotis et al [50] and Asloun et al [51]:…”

“…It is generally understood that at the interface between a polymer and a functionalized reinforcing material there exists an interphase with a known thickness and gradient of properties [27][28][29]. For simplicity's sake, the terms interface and interphase will be used interchangeably in this communication.…”

a b s t r a c tAdhesion of the reinforcement to the polymer matrix is essential for load transfer from the polymer matrix to the reinforcement material in fiber-reinforced composites. The reversible Diels-Alder reaction between a furan-functionalized epoxy-amine thermosetting matrix with a maleimide-functionalized glass fiber was used to impart remendability at the polymer-glass interface for potential application in glass fiber-reinforced composites. At room temperature the Diels-Alder adduct is formed spontaneously and above 90°C the adduct breaks apart to reform the original furan and maleimide moieties. Healing of the interface was investigated with single fiber microdroplet pull-out testing. Following complete failure of this interface, significant healing was observed, with some specimens recovering over 100% of the initial properties. Healing efficiency was not affected by the distance of displacement, with an overall average of 41% healing efficiency. Up to five healing cycles were successfully achieved. It is expected that a glass fiber-reinforced composite of maleimide-sized glass within a furan-functionalized network will demonstrate extension of fatigue life.
