Low flexural strength is one of the major drawbacks of most alternative raw materials particleboards. In thissense, we study the effect of incorporating a natural reinforcement, bidirectional jute fabric, on the final propertiesof particleboard based on rice husk and soy protein-based adhesive. The addition of two jute fabric layersimproved significantly the mechanical properties of the particleboards (flexure and tensile) exceeding the ANSIstandard established values for medium density particleboards for indoor use, without affecting the water absorptionand thickness swelling. Tensile strength values of reinforced boards were also numerically predictedaccording the rule of mixtures.
