Abstract:
The incorporation of natural lignocellulosic fibers in polymeric composites is very advantageous, because it allows to design materials with specific mechanical performance and to develop ecologically friendly products. In this sense, this work aims to evaluate the tensile behavior of polyester matrix laminated composites reinforced with raffia, jute and glass fibers. Samples with laminate orientation 0º/0º/0º of raffia/raffia/raffia (RRR), raffia/jute/raffia (RJR) and raffia/glass/raffia (RGR) were fabricated and then tested for tensile test, according to ASTM D3039/D3039M Standard. The results revealed that the replacement of the raffia by glass fibers entailed a slight increase of the tensile strength, on the other hand, the inclusion of glass fibers reflected in the improvement of this mechanical property, nevertheless, the results are coherent to those researched in the literatures.
