The present investigation addressed the use of treated and untreated sisal fibers (3cm, 30wt%, randomly distributed) as a reinforcement in bio-based composites. Sodium lignosulfonate (NaLS) was used to physically treat the sisal fibers and also as a macromonomer to prepare phenolic-type thermosets, namely, the matrices (LCs). The introduction of NaLS moieties on the surface of the fibers and in the...
