Abstract Scope |
There is a growing advance in the study of natural fibers to replace synthetic fibers. The specific properties of natural lignocellulosic fibers (NLFs) present performance comparable to synthetics. The use of kenaf fibers as reinforcement in polymeric matrices has shown excellent mechanical properties. The objective of this work is to evaluate through dynamic-mechanical analysis (DMA) of epoxy matrix composites reinforced with 0, 10, 20 and 30vol% of kenaf fibers. The curves of storage modulus (E’), loss modulus (E”), delta tangent (tan δ) and glass transition temperature (Tg) of the composites were analyzed. The results showed greater stability of the samples with the addition of reinforcement. The storage modulus (E’) ranged from 1542 to 6566 MPa, which shows the increased viscoelastic stiffness of the composite. There is a gradual reduction in the glass transition temperature as the kenaf fraction increased, associated with the effect of water on the epoxy polymer chains. |
