Fibre Matrix

An energy balance approach is proposed for the single fibre composite (or fragmentation) test, by which the degree of fibre-matrix bonding is quantified by means of the interfacial energy, rather than the interfacial shear strength, as a function of the fibre geometrical and mechanical characteristics, the stress transfer length, and the debonding length. The validity of the approach is discussed using E-glass fibres embedded in epoxy, both in the dry state and in the presence of hot distilled water.

The effects of surface treatment of a carbon fiber (CF) by Polyethylene-polyamine (PEPA) on the interfacial adhesion behavior and morphology of polypropylene/polystyrene (PP/PS) matrix blends filled CF composites were investigated. Effects of surface treated a commercial CF on mechanical properties are studied. Contact angle was measured to examine the changes in wettability of the carbon fiber. The chemical and morphological changes were characterized by using X-ray photoelectron spectroscopy (XPS). PP/PS/CF composites were fabricated with and without PEPA treatment, and their interlaminar fracture toughnesses were compared. The results showed that the interlaminar shear strength (ILSS) of composites has been greatly improved filled PEPA modification CF. The water contact angle of resin sample decreased 50% after addition of PEPA surface treated CF.

The performance of a composite material system depends critically on the interfacial characteristics of the reinforcement and the matrix material. In this study, the interfacial adhesion was tailored by the creation of textures on the glass fiber surface using inorganic-organic silane blends. A single-fiber microdroplet test was conducted to assess the interfacial properties between the textured glass surface and an epoxy matrix. The load–displacement curves from microdroplet tests were analyzed. The stress-based and energy-based micromechanic models of interfacial debonding and corresponding adhesional parameters (apparent and ultimate interfacial shear strength, friction stress, critical energy release rate, work of adhesion, and adhesional pressure) were applied for theoretical calculations. The results showed a clear trend for the impact of different silane blends on the interfacial properties. The specimens containing 75:25 and 50:50 of inorganic–organic silane blends show the most effective improvement in the interfacial adhesion properties between glass fiber and epoxy resin. Scanning electron microscopy was used to visualize the failure surface of the specimen after the microdroplet test. The scanning electron microscopic images indicated that the failure in the blend sized treated glass fiber–epoxy matrix specimen runs predominantly along the interphase and combines both cohesive failure in resin (the presence of some resin fragments) and adhesive failure (some bare fiber surfaces can be seen).
