Properties of particleboard made from kenaf (Hibiscus cannabinus L.) as function of particle geometry
An examination of particle geometry was carried out after the kenaf stems were chipped and flaked and the identified geometry was compared with that of rubberwood.

| Summary: | An examination of particle geometry was carried out after the kenaf stems were chipped and flaked and
the identified geometry was compared with that of rubberwood. The particle geometries were then clas�sified into several classes; 10 for kenaf core, 7 for kenaf bast, and 7 for rubberwood. The results indicate
that most of kenaf core particles were of rectangular or nearly rectangular shapes whilst kenaf bast was in
the form of curl and kneel form. Overall, board made from a combination of 70% rubberwood (RW) and
30% kenaf (K) was characterized by greater strength and stability than boards comprising 100% kenaf.
These results provide enough evidence that combining rubberwood with kenaf particles imparts better
mechanical and physical properties of the admixture RW–K board. Nonetheless, segregation of kenaf core
and kenaf bast is necessary since both materials produced different particle geometries thus require dif�ferent processing parameters. Between the two, kenaf core has better compatibility with rubberwood and
shows superior performance than kenaf bast. |
