TABORDA-RIOS, July Andrea; CANAS-MENDOZA, Luz Adriana  and  TRISTANCHO-REYES, José Luis. Comparative study of the mechanical properties of the polyester resin reinforced with bamboo fiber as the substitute material fiberglass. Dyna rev.fac.nac.minas [online]. 2017, vol.84, n.202, pp.35-41. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v84n202.57334.

This research was carried out a mechanical characterization of two types of composite materials: resin polyester reinforced with glass and bamboo fiber. It’s performed tensile, flexural and impact tests according to ASTM. The bamboo fibers were obtained manually and subjected to a chemical treatment with sodium hydroxide 5 % by weight for improving the compatibility polyester/fiber. The specimens were fabricated with mass concentrations of bamboo fiber of 11.07, 13.53 y 16.23 % and polyester reinforced with glass fiber of 10.11, 14.77 y 19.19 %. The mechanical properties of these composite materials were compared the polyester matrix without reinforcement in order to know the mechanical contribution of both fibers to matrix.
