Evaluation of the interfacial properties in the embedded-single-fibre coupon test

A refined method for estimating fiber and interfacial shear strength by using a single-fiber composite

“…From the slope and the intercept of a line approximating the Weibull plot, the parameters f3 and y were estimated by using equation (3). The results are shown in Table 3 together with the average fiber strength at gage length 10 mm calculated using equation (11).…”

“…A number of techniques [1][2][3] have been devised for estimating the fiber-matrix interfacial shear strength. Among these techniques, a fragmentation test [4][5][6][7][8][9][10][11] is one of the most popular experiments. In the fragmentation test, a fiber is broken into fragments by stretching a singlefiber composite axially until the fiber no longer breaks and the fragment lengths are measured.…”

Interfacial Effects on the Mechanical Properties of Glass/Phenolic Composites

“…However, the data on interfacial adhesion in fibre reinforced phenolic resin composites are limited, and there is a strong need to clarify the interfacial effects on the mechanical properties. In order to evaluate these effects, the fragmentation test is generally performed, using a single embedded filament composite sample [2][3][4]. This method can be applied for material systems with a ductile matrix because the fibre must break before the breakage of the matrix resin.…”

Effects of electrophoretically deposited carbon nanofibers on the interface of single carbon fibers embedded in epoxy matrix

“…Additionally, several researchers have used the fiber fragmentation test to investigate the effect of sizing, resin hardener, and environmental conditions on interface stress transfer [34][35][36][37][38][39]. Further review of these testing methods has been performed by Herrera-Franco and Drzal [1], Rao et al [27], Hamada et al [40] and Zhandarov and Mäder [12].…”
