Manufacture and properties of composite boards made from kenaf
The increasing demand for wood-based board products, together with the need to maintain wooden raw material resources, has become an important problem in Japan. Fear of shortage in wood supply from export countries has led to serious search for alternative raw materials, such as Kenaf (Hibiscus cannabinus L.). Kenaf is a fast-growing year-round economic plant used for coarse textiles and in papermaking. In this study, two types of composite boards were manufactured using kenaf stalk and sugi (Cryptomeria japonica D. Don) chips gathered from small diameter thinnings. Type 1 boards were produced using kenaf stalk and sugi chips, as core and surface materials, respectively. Type 2 boards were produced using kenaf stalk only in both core and surface layers that were oriented perpendicular to each other. The kenaf-composite boards were tested and evaluated the modulus of rupture (MOR), modulus of elasticity (MOE) in bending, intemal bond (IB), water absorption (WA) and thickness swelling (TS). Result of experiment indicated that technical feasibility of producing the two types of kenaf-composite boards with properties suited for particular end-uses.
