In last decades, the need for implementation of biodegradable materials is a showy concern for the planet earth because they contribute to the fight against environmental pollution and the valorization of plant resources. For this purpose, a composite developed with the tannin's binder and reinforcement of autranelle congolensis has been established. Throughout this work, two types of materials were manufactured under the same experimental. The implementation of biodegradable materials made with tannin's binder of autranelle congolensis (type1 materials) and synthetic materials based on Urea Formaldehyde (type2 materials). At the end of testing, it appears that type 1 materials are stiffer than type 2 materials: Indeed, the three-point bending tests performed on sample of type 1 materials when sizing rate varies between 25 and 78%, gave a Young's modulus varies between 43.832 and 466.652 MPa against 24.200 to 266.001 MPa for type 2 materials. A volume effect on the stiffness has established on the two types of materials: stiffness is increasing with the length between supports. For both materials, Young's modulus increases with the length between supports. The stiffness increases with temperature and the sizing rate. Materials having a high sizing rate are less resistant to moisture. The type 2 materials are resistant to moisture than type 1 materials.

Abstract
In last decades, the need for implementation of biodegradable materials is a showy concern for the planet earth because they contribute to the fight against environmental pollution and the valorization of plant resources. For this purpose, a composite developed with the tannin's binder and reinforcement of autranelle congolensis has been established. Throughout this work, two types of materials were manufactured under the same experimental. The implementation of biodegradable materials made with tannin's binder of autranelle congolensis (type1 materials) and synthetic materials based on Urea Formaldehyde (type2 materials). At the end of testing, it appears that type 1 materials are stiffer than type 2 materials: Indeed, the three-point bending tests performed on sample of type 1 materials when sizing rate varies between 25 and 78%, gave a Young's modulus varies between 43.832 and 466.652 MPa against 24.200 to 266.001 MPa for type 2 materials. A volume effect on the stiffness has established on the two types of materials: stiffness is increasing with the length between supports. For both materials, Young's modulus increases with the length between supports. The stiffness increases with temperature and the sizing rate. Materials having a high sizing rate are less resistant to moisture. The type 2 materials are resistant to moisture than type 1 materials. The binder developed with the tannin of autranelle congolensis has a gel time between 50 and 152 seconds.
