| Abstract Scope |
Natural Lignocellulosic fibers (FNL) in the last decades have stood out as reinforcement components in composites. The application of FNLs is justified by its high mechanical strength combined with its low economic value. Therefore, in this work, epoxy matrix composites reinforced with Amazonian guarumã fibers (Ischnoshiphon Koern) were investigated, little studied so far. Therefore, tensile and impact tests were performed for the volumetric fractions of 10, 20 and 30% following the international standards ASTM D3039 and ASTM D256-10, respectively. The results showed satisfactory mechanical properties, mainly for composites reinforced by 30% vol. fiber, with tensile strength equivalent to 53.75 MPa and modulus of elasticity equal to 1.69 GPa. On the other hand, its impact resistance approached 477 J / m, however most of the samples did not suffer total rupture of the specimen, validating the result only as a method of comparison between the volumetric fractions of the composite itself. |
