Mechanical Properties of Varieties of Kenaf (Hibiscus Cannnabinus) Stem
kenaf, moisture content, mechanical properties
Abstract
Due to the diversity in the use of kenaf, its processing and production, there is need to determine some mechanical properties of the kenaf stem so as to get a suitable database for design and mechanical features of the equipment and facilities for processing kenaf stem. This study was designed to investigate the effect of moisture content (mc) on mechanical properties of kenaf stems. Five common varieties of kenaf in Nigeria were identified and selected (Ife Ken 400, Ife ken D1 400, NHC 25 v 31, NHC 1 v 37 and Kuba 108). Samples were stored at room temperature for five weeks and moisture loss was monitored. Samples from each variety were cut into 30mm were prepared and placed horizontally between the crosshead of the Instron Testing Machine (Model 3369, 100KN, USA) to determine the mechanical properties (load at maximum tensile stress, tensile strain at maximum tensile stress, energy at maximum tensile stress and tensile stress at break) at 2mm/min.
