Abstract
Twine strength and Interfacial shear strength.xlsx
Sheet "Breaking force": Breaking force of the 2 mm hemp twine (10 specimens), with mean, standard deviation, and coefficient of variation.
Sheet "Pullout and tensile": Single-twine pullout test data (breaking force at embedded lengths of 10, 20, 40, 100, and 200 mm; n = 3) for untreated, water-treated, and SS-treated twine, with the calculated interfacial shear strength (IFSS) and critical fiber length. Tensile strength of the extruded composites (n = 5) for unreinforced, untreated, water-treated, and SS-treated specimens, with Kelly–Tyson model calculations.
