The che mical treatment of the mauve filament/fibers (3 cm of length) 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% filaments (w/w) and tested for water absorption, three-point bending, tensile and impact strength. Fiberglass composites were produced using the same methodology for comparison purpose. The results demonstrate the potential use of mauve filaments. For some properties, the mauve composites showed better mechanical properties than fiberglass composites (three-point bending and tensile). The treatment of the filaments had varied effect and did not improve the mechanical properties. However, for the water absorption was observed a reduction of 35% in composites with treated mauve filaments. 2018 artículo científico 0104-7760 https://www.redalyc.org/articulo.oa?id=74460165001 https://www.redalyc.org/journal/744/74460165001/ https://www.redalyc.org/journal/744/74460165001/html/ https://www.redalyc.org/journal/744/74460165001/74460165001.epub https://www.redalyc.org/journal/744/74460165001/movil 10.1590/01047760201824012453 en http://www.redalyc.org/revista.oa?id=744 CERNE application/pdf Universidade Federal de Lavras CERNE (Brasil) Num.1 Vol.24 |
