The objective of this study was to evaluate the polyester-based fiber composites reinforced with filaments/fibers of mauve treated with NaOH and maleic anhydride. The chemical treatment of the mauve filament/fibers (3 cm) was carried out, first with NaOH, followed by maleic anhydride. The resin used was ortho unsaturated polyester with addition of catalyst peroxide methyl ethyl ketone. The composites were prepared with 15% fiber (w/w) and tested for water absorption properties, three-point bending, tensile and impact strength. Fiberglass composites were made in the same way to compare with mauve composites. The results demonstrate the potential use of mauve fibers. For some properties the mauve composites perform better mechanical properties than fiberglass composites. The treatment of the particles had varied effect, but for the most mechanical properties, the treatment was harming. However, for the water absorption was observed a reduction of 35% in composites with treated mauve fibers.
