摘要: Brazil has played a leading role in the global cultivation of sugarcane, used production sugar and ethanol, which results sugarcane bagasse as agrowaste. This agroresidue generates electricity second-generation but colossal amount available allows for alternative applications. Currently, mechanized harvesting/unburn predominates over manual harvesting/burn. The present study was conducted this scenario investigated use fibers from unburned (SBU) bio-based composites. Phenolic thermoset chosen matrix due to its excellent properties. mechanization/unburn method variable length (this study: 1/3/5 cm, 30 wt%). SBU characterized detail, highlighting characterization via inverse gas chromatography (IGC, provides information regarding polarity groups on surface fibers). Briefly, composition shows no significant differences compared burnt (SBB), IGC showed that more polar than SBB, favors intermolecular interactions then adhesion with phenolic matrix. Composites reinforced 3- 5-cm presented storage modulus higher unreinforced thermoset, impact strength all composites (up 45%). set points applications such rigid packaging, non-structural parts buildings automotive vehicles, increases agrowaste within circular bioeconomy.
