Sugarcane Bagasse Fibers Treated and Untreated: Performance as Reinforcement in Phenolic-Type Matrices Based on Lignosulfonates

In this study, fragile thermoset phenolic-type polymers were chosen as composite matrices that were reinforced with sugarcane bagasse fibers, an agro-residue widely available across the world, which has motivated the search for new applications for this fiber. Lignosulfonate (SL), a macromolecule obtained from lignocellulosic biomass and having phenolic rings in its chemical structure, was used as a substitute for phenol in the synthesis of...
