Epoxy resin was used as a binder, with methanol added to enhance processing and mechanical performance. The effects of particle size (<60 mesh and >60 mesh), five methanol concentrations (1.5%–3.5%), and binder-to-particle ratios (1.4:1 to 2.2:1) were evaluated. Boards were pressed at 25°C for 15 minutes. Physical and mechanical properties were analyzed, including density, moisture content, thickness swelling, tensile strength, yield strength, and modulus of elasticity derived from tensile testing. Results showed densities ranging from 0.568 to 0.942 g/cm3, moisture content below 6.6%, and zero thickness swelling after 24-hour immersion. The best mechanical results reached 11.96 MPa for tensile strength and 125.82 MPa for yield strength, with a maximum modulus of elasticity of 190.09 MPa. While MOE values were derived from tensile testing and not flexural analysis as required by SNI 03-2105-2006, results indicate cogon grass particleboards are promising for indoor use.}, number={3}, publisher={Gazi University}
