dc.description.abstract1This study investigated the influence of the surface treatment of curaua fibres (Ananas erectifolius) on the morphological, thermal and mechanical properties of polyester composites when the treated fibres (10 wt-%) were added. The following treatment agents were assessed: 10% Ba(OH)2, 14% Ca(OH)2, 5% NaOH, 10% KOH and 5% silane. The treatments removed amorphous components, thereby increasing the crystallinity of the fibres. Among the alkali treatments, KOH gave the highest crystallinity index (67.09%), Ca(OH)2 had the best tensile strength (19 MPa) and Ca(OH)2 treatment resulted in the highest composite thermal stability (315°C). Fibres treated with Ba(OH)2 resulted in the composite with the greatest resistance to impact (55 vs 10 J m−1 for the neat matrix). Finally, the silane-treated fibres resulted in composites with a better performance than the other treatments. There was a prominent pattern of improved performance for the silane-treated fibre composites in all the analyses performed in this study.pt_BR
