“…Las propiedades de un MC dependen de muchos factores como la resistencia y orientación del material de relleno en el compuesto, los tratamientos superficiales de las fibras, el procedimiento de fabricación del compuesto y el tipo de matriz, entre otros (Udaya Kiran, et al, 2007).…”

“…Sin embargo, y a pesar de que en este trabajo fue utilizado el modo de fabricación por moldeo manual, que no permite contenidos de fibra por encima del 14-15% (Dittenber, et al, 2012), se lograron mejoras sensibles en las propiedades mecánicas de los MC respecto de las que se observaron en los especímenes sin tratar. Debido a que el incremento en el porcentaje de fibra mejora la unión con la matriz y facilita la distribución de las cargas de tensión (Udaya Kiran, et al, 2007), sería de esperar que, usando otra técnica de fabricación que permita incrementar el porcentaje de fibra, los MC fabricados con FSP modificadas lograrían desempeños mecánicos superiores. De hecho, en la tabla 1 se puede observar que para las FB (carga del 20%), hay un incremento en la resistencia última a la tracción y del módulo de Young.…”

* Autor a quien debe ser dirigida la correspondenciaRecibido Ene. 30, 2014; Aceptado Abr. 22, 2014; Versión final recibida May. 7, 2014 Resumen Se fabricaron piezas de materiales compuestos mediante la técnica de moldeo manual con fibras del seudo tallo de plátano (FSP), fique y vidrio en una matriz de poliéster. Las FSP fueron tejidas y analizadas sin tratamiento y tratadas químicamente con anhídrido acético, epiclorhidrina y su mezcla. El objetivo fue caracterizar y comparar los compuestos obtenidos mediante ensayos de tensión, impacto, capacidad de absorción de agua y micrografías. El valor promedio de la tensión a la ruptura de los materiales compuestos con FSP tratadas aumentó respecto a las FSP sin tratamiento y al fique. Además presentaron el menor incremento de peso en las pruebas de absorción de agua. Este comportamiento se atribuyó a una mayor hidrofobicidad de las FSP tratadas. Esto a su vez produjo mejor adhesión con la matriz, como se corroboró en las micrografías que mostraron menor deslizamiento en las superficies de corte. Palabras clave: fibra de banano/plátano, anhídrido acético, epiclorhidrina, compuesto de poliéster Polyester Composites Reinforced with Banana/plantain (Musa paradisiaca) Fiber Chemically Modified. Comparison with Fiberglass and Fique (Furcraea andina) AbstractSamples of composites were prepared using the hand lay-up technique with banana seudo-stem fibers (BSF), fique and glass, in a polyester matrix. The BSF was woven and analyzed untreated and chemically treated with acetic anhydride, epichlorohydrin, and their mixtures. The aim of this work was to characterize and compare the composites obtained using tensile tests, impact test, water absorption capacity and micrographs. The average value of tensile strength for the composite with treated BSF increased respect to untreated BSF and fique. Also, according to the water absorption tests, they showed the smallest weight increase. This finding was attributed to the higher hydrophobicity of the treated BSF. This in turn improved the adhesion with the matrix, as it was corroborated by the micrographs that showed lower displacement on the tensile fracture surfaces.

“…O'Dell (1997) used non-woven jute fibers to prepare UPE panels and found that TS, tensile modulus, and flexural modulus of the jute specimens were half the values of the glass fiber-reinforced UPE composites; IT and TS were also lower. The comparison of sisal, jute, flax, and glass fiber-reinforced UPE composites has been carried out, and the results suggested that among the three natural fibers reinforced composites, the jute-reinforced UPE composites exhibited the best FS and TS, and the worst IT (Rodríguez et al 2005;Udaya Kiran et al 2007). In another investigation, Hill and Abdul Khalil (2000) have used non-woven mats of random coir and oil palm fibers (0 to 55 wt.%) to reinforce UPE using compression moulding, and FS values of all the composites were found to be lower than those for plain UPE at all fiber contents.…”

Unsaturated polyester (UPE) composites reinforced with natural fiber as non-structural materials have been used in engineering. In this study, three different types of coir-reinforced UPE consisting of coir non-woven needle mat (CNM), coir mesh (CM), and coir rope (CR) were produced, and the mechanical properties, such as flexural strength (FS), tensile strength (TS), and impact toughness (IT), were investigated. With the exception of FS, CR-reinforced UPE composites exhibited better mechanical properties, mainly due to good directionality of the coir fibers. Dynamic mechanical analysis (DMA) was also carried out to analyze the composite performances under wide temperature ranges. All the tests confirmed the beneficial effect of coir on the UPE matrix, noting that composites with higher toughness perform better in most applications.

“…Venkateshwaran et al [10] reported that an increase in banana fiber length of up to 15 mm and a 16% weight ratio increases the tensile strength and modulus of a banana/epoxy composite. However, in order to achieve higher mechanical properties, Udaya et al [11] suggested an optimal fiber length and fiber weight ratio of 30 mm and 57%, respectively. However, the optimal findings for fiber treatment and fiber loading are still inconsistent.…”

Banana fiber has a high potential for use in fiber composite structures due to its promise as a polymer reinforcement. However, it has poor bonding characteristics with the matrixes due to hydrophobic–hydrophilic incompatibility, inconsistency in blending weight ratio, and fiber length instability. In this study, the optimal conditions for a banana/epoxy composite as determined previously were used to fabricate a sandwich structure where carbon/Kevlar twill plies acted as the skins. The structure was evaluated based on two experimental tests: low-velocity impact and compression after impact (CAI) tests. Here, the synthetic fiber including Kevlar, carbon, and glass sandwich structures were also tested for comparison purposes. In general, the results showed a low peak load and larger damage area in the optimal banana/epoxy structures. The impact damage area, as characterized by the dye penetration, increased with increasing impact energy. The optimal banana composite and synthetic fiber systems were proven to offer a similar residual strength and normalized strength when higher impact energies were applied. Delamination and fracture behavior were dominant in the optimal banana structures subjected to CAI testing. Finally, optimization of the compounding parameters of the optimal banana fibers improved the impact and CAI properties of the structure, making them comparable to those of synthetic sandwich composites.
