Resumen:
In this work vinylestermatrix composites reinforced with woven jute
fabrics were investigated. The effect of a simple fiber treatment with silicone on the
mechanical and viscoelastic response in comparison to traditional treatments was
analyzed. Unless the composite with acetylated fibers, all composites exhibited
higher values of rubbery storage modulus than the matrix. All treated fiber
composites have similar damping capacities. Furthermore, silicone had a plasticizing
effect on the vinylester matrix. The composites with washed fibers and with fibers
treated with silicone exhibited slightly higher stiffness and strength values than other
treated fiber composites. In addition to its experimental simplicity, the treatment
with silicone also allowed us to obtain the composites with best combination of
stiffness, strength, and toughness.
