Effects of gamma irradiation on some mechanical properties of novoloid fibers

Electrodeposition of Nickel onto 12K Carbon Fibre Tow in a Continuous Manner

“…In addition, a simple, SEM-supported knot test was used to qualitatively evaluate (and compare) the strength of interfacial adhesion of Ni (potentially, also its ductility) to the surface of CF filaments. The knot test 28,29 is a mechanical bending experiment, in which a piece of NiCCF tow is bent sharply enough (a constant load of 500 g for 5 s was applied to tie the NiCCF knots in this work) to break the metal coating on the tension side of the bend. Then, the knots are qualitatively examined and compared by the SEM method.…”
