A comparison of tensile properties of polyester composites reinforced with pineapple leaf fiber and pineapple peduncle fiber

Abstract

A comparison of tensile properties of polyester composites reinforced with pineapple leaf fiber and pineapple peduncle fiber Abstract. Pineapple fiber which is rich in cellulose, relatively inexpensive, and abundantly available has the potential for polymer reinforcement. This research presents a study of the tensile properties of pineapple leaf fiber and pineapple peduncle fiber reinforced polyester composites. Composites were fabricated using leaf fiber and peduncle fiber with varying fiber length and fiber loading. Both fibers were mixed with polyester composites the various fiber volume fractions of 4, 8 and 12% and with three different fiber lengths of 10, 20 and 30 mm. The composites panels were fabricated using hand lay-out technique. The tensile test was carried out in accordance to ASTM D638. The result showed that pineapple peduncle fiber with 4% fiber volume fraction and fiber length of 30 mm give highest tensile properties. From the overall results, pineapple peduncle fiber shown the higher tensile properties compared to pineapple leaf fiber. It is found that by increasing the fiber volume fraction the tensile properties has significantly decreased but by increasing the fiber length, the tensile properties will be increased proportionally. Minitab software is used to perform the two-way ANOVA analysis to measure the significant. From the analysis done, there is a significant effect of fiber volume fraction and fiber length on the tensile properties.

Suitability characterization of novel cellulosic plant fiber from Ficus benjamina L. aerial root for a potential polymeric composite reinforcement

“…Two peaks are observed in the range of 15–18° and 21–23° for most of the natural plant fibers in the earlier studies. [ 56 ] This investigatory result also validates the outcomes of chemical composition analysis, proving the existence of crystalline and amorphous components in the fiber.…”

A review on the extraction of pineapple, sisal and abaca fibers and their use as reinforcement in polymer matrix

“…The mechanical properties of PALF-polyester composites at different PALF loading were studied by different researchers [118]. They report that the mechanical properties (tensile strength, tensile modulus, elongation at break, Young's modulus, impact strength, and shear strength) of neat polyester increases with PALF [wt%] and this iomprovement is attributed to the enhancement of fiber-matrix interaction with fiber loading [119,120]. However, the mechanical properties are found to diminish at high fiber loading, due to poor dispersion of fiber in the matrix.…”

Suitability examination of novel cellulosic plant fiber from Furcraea selloa K. Koch peduncle for a potential polymeric composite reinforcement

“…Polyester composites reinforced with pineapple leaf and pineapple peduncle fibers results showed that the best‐performing pineapple fiber was the peduncle fiber, which included 4% fiber volume fraction and fiber length of 30 mm. Overall, the tensile qualities of pineapple peduncle fiber were found to be superior to those of pineapple leaf fiber 16 …”

“…Overall, the tensile qualities of pineapple peduncle fiber were found to be superior to those of pineapple leaf fiber. 16 In the present investigation, a novel plant fiber from Furcraea selloa K. Koch peduncle has been introduced in the quest of exploring a new cellulosic plant fiber for composite fabrication. Hence an effort has been made for characterization of the fiber through various analytical methods including physical (density, diameter), chemical (cellulose, hemicellulose, lignin, wax, ash, and moisture) mechanical (tensile strength/modulus), thermal (thermal stability) and morphological (surface roughness) analysis.…”
