| Abstract Scope |
The disadvantages of natural lignocellulosic fibers (NLFs) for applications in composites of polymeric matrices led to the need to study new treatments to optimize the compatibility between these materials through surface treatments. Recent studies show that the functionalization of both synthetic and natural fibers with graphene oxide (GO), has become an efficient solution against this disadvantage. The present work aimed to study the Izod impact energy absorption capacity of epoxy matrix composites reinforced with curaua fibers treated with GO. The analysis was carried out within three groups, varying the volumetric fraction of fibers between 20, 30 and 40% vol in two conditions: composites with curauá fibers (control group) and composites with curauá fibers functionalized with 0.1% GO. The percentage of fibers was predominant for increasing the energy absorption capacity while the functionalization with GO was effective in reducing the dispersion of results, homogenizing the properties of the composite. |
