“…Moreover, it was found that adsorbed water molecules could migrate towards the sizing/GF interface through the thin sizing, resulting in the dissolution/decomposition of polysiloxane [15,26] or the growth of a silica gel layer [27]. On the other hand, it is known that surfactant adsorbed on glass plates can be replaced with polymer solution or washed away by solvents, even though Jones et al found that solvent extraction could not remove sizing resins efficiently [28,29]. Recently, it was revealed by Mäder et al that extracting only γ-APS sized GFs with hot water led to a great increase in the local interfacial shear strength and the energy release rate of epoxy/GF single fibre model composite since water washed off excessive physically adsorbed γ-APS [16].…”

Polypropylene (PP) compatibly sized glass fibres (GFs) were treated with boiling water and toluene, respectively, to reveal the interactions of water and toluene with different components in the sizing of sized GF and their influences on the interfacial adhesion strength of GF/PP model composites.Compared to control GF/PP model composites, about 30% increase of interfacial adhesion strength was achieved for composites with water-treated GF, whereas a small decrease of interfacial adhesion strength was revealed for composites with toluene-treated GF. X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, Zeta-potential measurement, and water contact angle measurement demonstrated that the boiling water treated GFs posses a more polar and hydrophilic surface with homogeneously distributed derivatives of γ-aminopropyltriethoxysilane, which is related to a higher interfacial adhesion strength for water treated GF/PP model composites.In contrast, hot toluene treated GFs led to a more hydrophobic surface with low molar mass PP and surfactants enriching on the outermost surface.

“…In order to improve the adhesion between the carbon fibres and the polymer matrix, different surface treatments of carbon fibres can be done, such as plasma treatment or surface oxidation; the most common is the use of polymer sizing [1][2][3][4][5]. In that case, the sizing must be compatible with the matrix [6][7][8][9][10]. Moreover, the mechanical behaviour of the sizing has an influence on the mechanical properties of the final composite in terms of fatigue performance [11], flexural strength and fracture toughness [12].…”

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. A B S T R A C TCarbon fibres are sized for use in the reinforcement of composite materials. The purposes for sizing include improving yarn cohesion, which is necessary for the weaving process, and increasing the adhesion between the fibres and the matrix. Nevertheless, during weaving, some fibrillation can occur, and that has detrimental effects on the weaving productivity and on the composite's properties. The purposes of this research were: (a) to determine whether abrasive wear between sliding fibres would modify the sizing and (b) to study the influence of sizing on the friction between fibres. The same type of carbon fibre was subjected to different desizing processes. The coefficient of friction between single fibres was obtained before and after desizing. The effects of sizing and sliding distance on frictional behaviour were investigated, and are related to the observed the wear of sizing layer. In fact, it increased with sliding distance and induced a decrease in the coefficient of friction. Moreover, an efficient desizing process induced a decrease of the coefficient of friction.

“…The effectiveness is confirmed by the off-axis strength which is usually close to the strength of the polymer [78,79]. It has been also reported that the presence of sizing may improve the wetting of the fiber by the matrix resin and protect its reactivity [80,81]. Wetting is a prerequisite to good adhesion [82].…”
