Pineapple leaf fiber

Laminated biocomposites were prepared from biodegradable PLA and pineapple leaf fibers by compression molding by the film stacking method (35). The pineapple leaf fibers were either untreated or... 

Both silane- and alkaU-treated fiber reinforced composites show superior mechanical properties in comparison to imtreated fibers. The incorporation of the pineapple leaf fibers effect a considerable increase of the storage modulus, i.e., stiffness. Also the heat defection temperature of the composites was significantly higher.

George et al. (1996) treated pineapple leaf fiber with polymethylene-polyphe-nyl-isocyanate (C15H10N2O2) solution at 50°C for 30 min to improve the fiber-matrix interfacial adhesion. Comparing silane and isocyanate-treated wood fiber-PS composites, it was reported that isocyanate treatment was more effective than silane treatment in enhancing the mechanical properties of cellulose fiber-PS composites (Maldas et al. 1989). 

Pineapple Leaf Fibers and PALF-Reinforced Polymer Composites... 

Abstract Pineapple leaf fibers (PALF) have long been known as textile materials in many countries. Despite being mechanically excellent and environmentally sound, PALF are the least-studied natural fibers, especially for reinforcing composites. This article presents a survey of research works carried out on PALF and PALF-reinforced composites. It reviews PALF extraction, fiber characterization, and PALF applications, modification of PALF, and manufacture and properties of PALF-reinforced composites. With increasing importance of pineapple and pineapple plantation area, value-added applications of PALF as reinforcing fibers in polymer composites must be developed in order to increase resource potential of pineapple and consequently energize the utilization of PALF.

The leaves of the pineapple plant yield strong, white fine silky fibers. Pineapple leaf fibers have a potential to form composites because they are rich in cellulose, relatively inexpensive, and available abundantly. 

Melt mixing and solution mixing methods were used to prepare short pineapple leaf fiber-LDPE composites. Effects of fiber length, content, and orientation on the mechanical properties have been studied. The mechanical properties were improved while the elongation at break was found to be reduced. Longitudinally oriented composites describe better properties compared to transversely and... 

The tensile and flexural behaviors of pineapple leaf fiber-PP composites as a function of volume fraction were investigated. The tensile modulus and tensile strength of the composites were found to increase with fiber content in accordance with the rule of mixtures. The flexural modulus and stress of the composites increased with the content of fiber but these values were lower than the reported values by other researchers. The lower values for flexural modulus and stress were ascribed to the presence of fiber-fiber interactions, voids, and dispersion level [10]. 

The density of sisal fiber varies from 1.35 to 1.45 g/cm. Literature shows that sisal fiber exhibits tensile strength in the range of 400-700 MPa, which is nearly similar to many commercially used natural fiber such as jute, flax, banana, and sun hemp. Therefore, we can use sisal for commercial application as we can use jute, flax, banana, pineapple leaf fiber, etc. The mechanical properties of some of the natural fibers and other mineral fibers are shown in Table 22.4.
