“…It follows that τ is a function of the average fragment length at saturation, truels¯. Because there is no accepted method for determining σf(lc) [30,31], estimates of τ can vary widely. For this study, truels¯ was used as an acceptable surrogate for τ since it depends explicitly on this parameter.…”

This study focuses on understanding the effect of cellulose nanocrystals (CNCs) on glass fiber/epoxy interfacial interactions. The glass fibers (GF) were coated with solutions containing cellulose nanomaterial. The parameters that were investigated were the CNC surface chemistry, concentration, and dispersing medium, i.e., aqueous solution only versus emulsions. To determine the effect of the CNC coatings on the interfacial adhesion, specimens of a single GF in an epoxy matrix were prepared for GF coating by varying the coating formulations. The interfacial shear stress (IFSS) was determined by the single fiber fragmentation test (SFFT). Following the SFFT, the samples were investigated by cross-polarized microscopy in order to understand the fracture modes which are related to the nature of the interphase. According to the SFFT data and photoelastic fracture patterns, both the emulsion and aqueous coatings containing cellulose nanocrystals functionalized with methyl(triphenyl) phosphonium (CNCPh) improve the IFSS in comparison to coated GFs without CNCs.

“…Several micromechanical techniques have been proposed for measuring the interfacial properties in various ber reinforced composites [2 -7]. The IFSS can be assessed conventionally by single-ber pullout testing [8 -12], single-ber fragmentation testing [13][14][15][16][17][18], microindentation testing [19], off-axis tensile testing [20] and related methods, which provide information on the interfacial properties [7,20]. The single-ber pullout test has been used because it can measure IFSS between the ber and matrix directly and simply.…”
