Gypsum is a mineral binder, widely use in the manufacture of gypsum plasterboard for panelling purpose. A study was conducted on the feasibility of utilising oil palm stem fibres as the reinforcing material in the manufacture of gypsum-bonded particleboard. In the first part of the study, nine series of GBP were made at the densities 1000, 1150 & 1300 kg/m³ and wood:gypsum ratios 1:2.5, 1:3.0 and 1:3.5. Results showed that boards produced at a minimum density of 1150 kg/m³ and wood:gypsum ratio 1:2.5 satisfied the physical and mechanical requirements of commercial GBP. In the second part of the study, six series of GBP at target density 1150 kg/m³ were made, using different particle sizes and mixed dried and undried oil palm particles. The physical and mechanical properties of the boards produced are discussed.
