Improvement of flexural properties and dimensional stability of rice husk particleboard using wood strand from (azadirachta excelsa) in face layer / Muhamad Zahir Nazri
Improvement of flexural properties and dimensional stability of rice husk particleboard is targeted in this study. Five ratios of Azadirachta excelsa (0, 10, 20, 30 and 40%) at face layer were tested. Further work was done with 40% Azadirachta excelsa content with random and aligned arrangement....

| 總結: | Improvement of flexural properties and dimensional stability of rice husk
particleboard is targeted in this study. Five ratios of Azadirachta excelsa (0, 10,
20, 30 and 40%) at face layer were tested. Further work was done with 40%
Azadirachta excelsa content with random and aligned arrangement. The results
showed significant (p ≤ 0.05) improvement in flexural strength (MOR and MOE)
as the face layer percentage increases. The dimensional stability (water
absorption and thickness swelling) with 40% give the best performance.
Arrangement of strength has no significant effect. Overall there is potential to
improve the flexural and dimensional stability with variation of strands at face
layer. |
