CARLOS, Segovia, et al. Study of the Mechanical Characteristics of Bamboo Fibers for the Manufacture of Automotive Parts. Rev Politéc. (Quito) [online]. 2023, vol.52, n.1, pp.55-62. ISSN 2477-8990.

The studies of composite materials play an important role in engineering, metallurgy, mechanical applications and currently an alternative in the manufacture of automotive parts. Natural fibers reinforced with polymers have certain benefits such as low cost, low weight, are renewable and are easy to process. The objective of this research was to characterize the composite material with polymers reinforced with bamboo fibers, for its application in the manufacture of automotive parts. For the tests, specimens were made of bamboo fiber composite material in proportions of 75% and 60% with epoxy resin in proportions of 25% and 40% arranged in 2 and 3 layers. The results in the proportion of bamboo fiber (75%) - epoxy resin (25%) showed a better mechanical bending behavior by 7.7% compared to other natural fibers such as natural long cabuya fiber with fiberglass, which translates into an increase in stiffness of the characterized materials, thus corroborating that it is a potential reinforcement of alternative hybrid material for automotive applications. The tensile stress results were validated using the FEM finite element method.
