Investigation of Thermal Conductivity and Mechanical Properties of Gypsum Particleboard Reinforced with Fiber-Reinforced Polymers

Engineering composites such as particleboard have widespread use in various fields, but low mechanical strength and sensitivity to environmental factors limit the performance of these materials. In this study, mechanical and thermal properties such as thermal conductivity, density, flexural strength, and modulus of elasticity of wood-reinforced gypsum boards reference boards and fiber-reinforced polymer (FRP) applied wood-reinforced gypsum boards were investigated according to wood and bark ratios. The results showed that the material composition significantly affects these properties. Thermal conductivity increased with increasing wood ratio, while it decreased with increasing bark ratio. FRP application increased thermal conductivity in all samples and was found to be related to density. In terms of density, samples with high wood ratios were heavier and denser with FRP. While flexural strength decreased with increasing bark ratio, FRP application increased the flexural strength. These findings show the positive effects of FRP on wood-reinforced gypsum boards boards and its high performance potential in the construction industry.
