“…Otro aspecto a resaltar es que usualmente las bajas proporciones de fibra en el MC, están asociadas a un pobre comportamiento mecánico (Pothan, et al, 1997). 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.…”

* 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.

“…9). Our earlier studies indicated that the acceptor number, which is indicative of the electron accepting ability, is found highest for bres treated with the silane A151 [10]. The E T (30) parameter which is indicative of the overall polarity is also found to be maximum for bres treated with the silane A151.…”

Among the various factors, the nal performance of the composite materials depends to a large extent on the adhesion between the polymer matrix and the reinforcement and therefore on the quality of the interface. To achieve optimum performance of the end product, suf cient interaction between the matrix resin and the cellulosic material is desired. This is often achieved by surface modi cation of the resin or the ller. Banana ber, the cellulosic bers obtained from the pseudo-stem of banana plant (Musa sepientum) is a bast ber with relatively good mechanical properties. The ber surface was modi ed chemically to bring about improved interfacial interaction between the ber and the polyester matrix. Various silanes and alkali were used to modify the ber...

“…Different natural fibers such as jute, coir, banana, straw, palm, and others have been previously investigated to be used as natural reinforcements in composites [5][6][7][8][9]. Moreover, natural fibers were used as natural hybrids by a proper combination of natural reinforcements, that is, hybridization as reported in [10][11][12][13].…”

The aims of this research are to investigate the effect of different surface treatment methods on the different properties of date palm fiber (DPF) compared to raw DPF fibers such as surface morphology, density, thermal stability, and tensile properties. The first surface treatment is called surface hand cleaning which can be carried out by cleaning the fibers by soft sand cloth; the second one is the same as the first one after DPF heat treatment in the furnace at 100 ∘ C for 1.5 h and the third one is by chemical treatment with 1% NaOH at 100 ∘ C for 1 h. The results showed that the mechanical performance of DPF was enhanced by the different treatments and the chemical treatment has pronounced effect on the behavior of DPF. Raw fibers showed the highest variability and presented the lowest value of Weibull modulus, whereas the fibers showed less variability by carrying out the different treatments. Moreover, using soda treatment cleans the fiber surface which causes fibrillation and therefore the tensile strength of the fibers increases.
