6 Justification The tropical forest will be disappearing at the rate of million ha/year All wood industries in Malaysia is getting a serious problem on getting the raw materials. Plantation species as a raw material for future.

7 Objectives 1. To study the physical and mechanical properties of particleboard using A. mangium as a raw material 2. To compare the physical properties of A.mangium particleboard to mixed wood particleboard 3. To compare the mechanical properties of A.mangium particle board to mixed wood particleboard

8 Why I choose A.mangium ? Acacia mangium is a fast-growing and evergreen species. Extremely vigorous growth (annual wood volume increment of over 30 cubic meters per hectare on favorable sites) A.mangium falls under the light hardwood classification with mechanical properties MOR (modules of Ruptures): 74.5N/mm 2 MOE (Modules of Elasticity ): 9908N/mm 2

9 Relative freedom from diseases Adapted to a wide range of acidic soils (pH ). Rotation years is very small and Available plenty in Sabah.

13 Sampling  Acacia logs were extracted from Paitan forest plantation in Kudat, Sabah  The age of A.mangium used is between 6-8 years.  While mixed hardwood like Shorea spp., Dryobalanops spp., and other timbers (O.T) were obtained from neighboring sawmills and plywood mills such as Sri Jambongan and Seraya Sawmill.

18 RESULTS AND DISCUSSION

19 Density Comparison between A.mangium & Mixed Hardwood Board

20 Thickness Swelling Comparison between Unsanded A.mangium and Mixed Hardwood Boards

21 Bending Strength Comparison between Unsanded A.mangium and Mixed Hardwood Boards

22 Internal Bond Comparison between Unsanded A.mangium and Mixed Hardwood Boards

23 Surface Bond Comparison between Unsanded A.mangium and Mixed Hardwood Board

24 Screw Holding Comparison between Unsanded A.mangium and Mixed Hardwood Boards

25 Density Comparison between Sanded A.mangium & Mixed Hardwood Board

26 Thickness Swelling Comparison between sanded A.mangium and Mixed Hardwood Boards

27 Bending Strength Comparison between Sanded A.mangium and Mixed Hardwood Boards

28 Internal Bond Comparison between Sanded A.mangium and Mixed Hardwood Boards

29 Surface Bond Comparison between Sanded A.mangium and Mixed Hardwood Boards

35 CONCLUSIONS  The physical and mechanical properties of the particle board produced from A. mangium proved that A.mangium can be used as a single raw material in producing particle board.  The physical properties of the mixed wood and A. mangium, A. mangium have lower density compare with the mixed wood and the swelling properties are almost the same.

36 Cont…  The mechanical properties of A. mangium and mixed wood, A. mangium have better bending strength and screw holding compare to mixed hardwood particle board and in terms of the surface bond and the internal bond the properties are almost the same.

37 Contributions of the study  This research has successfully proved that Acacia mangium can be an option in particleboard industry especially in Sabah.  The study states that A.mangium can be used as a single raw material for making particle board  It prove that particle board produced from A.mangium can be compete with particle board produced from other species as a raw material  A step towards utilizing the A.mangium fully from the plantation
