KEY WORDS:

Biomass, sustainability and adhesion

SUMMARY:

The increase in population and the growing need for materials have intensified the search for solutions for the use of waste generated by the productive sector. Biomass, especially agricultural waste such as rice husk, has stood out as a sustainable alternative for energy generation and production of new materials. Rio Grande do Sul (RS) is the largest rice producer in Brazil, generating large quantities of rice husk, a waste with high potential for different industrial applications. Rice husk (RH) is an abundant agricultural waste that can be used in several applications, from fertilizers in agriculture to civil construction and the production of thermoplastic and thermoset composites. These composites, formed by RH and polymers such as polypropylene (PP), can have their mechanical properties improved, although challenges such as the incompatibility between hydrophilic RH and hydrophobic polymer matrices need to be overcome. The objective of the study is to evaluate the mechanical properties of PP composites reinforced with RH, comparing the performance of composites made with in natura and ground RH. Research shows that although the addition of CA improves some properties, such as the modulus of elasticity, it can also reduce the impact and tensile strength due to poor adhesion between the fiber and the polymer matrix. To improve this adhesion and, consequently, the properties of the composites, several methods of treating the surface of CA are suggested.
