The results show that the variation in the swelling rate of some samples analysed describes a sinusoid with values higher than those recommended by the AINSI A 208.1 1999 standard. The use of these panels in a dry environment is therefore strongly recommended. The Young's modulus of elasticity (YME) and the breaking Modulus of Rupture (MOR) of the composite materials are between 0.91 and 2.31 GPa and 5.39 and 16.43 MPa. These values meet the 1999 ANSI 208.1 standard, which requires that the YEM and MOR of insulation boards in buildings be greater than or equal to 550 MPa and 3 MPa, respectively. Deformation at break varies between 8.40 and 13.05 mm. These values explain the non-ductile behaviour of these materials. Finally, the evolution of the mechanical properties of the material (Flexural Modulus of Elasticity (FME), MOR and deformation) as a function of the binder rate and the particle size distribution indicate that the presence of starch in the small particle sizes (≤ 0.425mm) favours the increase in the rigidity of the material. The breaking strength of the material (small granulometry) is greater with starch proportions ranging from 10 to 15%. The presence of the binder in the composite, whatever the granulometry, changes the behaviour of the material by increasing its deformation at breakage. With regard to flexural behaviour, typha particles with a particle size between 0.425 mm and 1.25 mm with a binder content of 10% to 15% are therefore more ductile. With these characteristics, the formulations M1 (10% starch; 0.425 mm) and M4 (15% starch; 0.425 mm) indicate the best mechanical properties.
