We study the use of husk rice as filler; in this case we try to improve the mechanical properties of recycling rubber starting from waste tires. Fibbers or lignocellulose fillers as matrix polymeric matrix reinforcement at the moment have a great technological and scientific interest because of their good specific properties. In comparison to others fibers o inorganic fillers, they have properties such as low cost, it is recyclable, biodegradable and with similar density to matrix polymeric. A kind of lignocellulose fibber as husk rice has great advantages as its great refuse in agricultural industry. The recycling of husk rice is an environment problem concerning to agricultural industry. On the other hand, the rubber matrix that we use comes from recycling tires. The recycling of tires is an environment problem concerning to industry. Moreover the obvious environment reasons, the suitability of reclaim, recycling and use of waste generated for human activity is a fact. In the case of used tires these reasons come together with the laws in Europe that force to recovery of different parts of used automobiles. We intend to obtain a new composite material using two industrial wastes, so we get a useful material starting from devaluated materials. We and can study its influence of use husk rice as reinforced agent in a rubber matrix. Husk rice has a great influence in de mechanical properties, mainly in elasticity modulus. We can observe a decrease of tensile strength and increase of elasticity modulus as it increases the proportion of husk rice.
