Micro-mechanical analysis of the pineapple-reinforced polymeric composite by the inclusion of pineapple leaf particulates

Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications, 2021
The present study is focused on investigating the effect of the micro-mechanical properties of the natural fiber- (pineapple leaf fiber) reinforced polymeric composites by the addition of pineapple leaf micro-particulates. For the investigation, a two-step approach has been used.

Modification of pineapple leaf fibers with aminosilanes as adsorbents for H2S removal

Chemosphere, 2021
Pineapple leaves were used as a natural fiber source to prepare various modified microcrystalline cellulose (MCC) samples as sorbents for H2S sorption. Pineapple leaf fibers were first extracted from pineapple leaves, followed by hydrolyzing to produce MCC before various modifications using primary amine (3-aminopropyltrimethoxysilane, APS), secondary ...

Functionality and characterization of modified starch films with pineapple leaf fibers

International Journal of Biological Macromolecules, 2023
The objective of this work was to modify banana starch with pineapple leaf fibers (PALF) and its production of biodegradable films. The reaction conditions of the starch modification were a Starch/PALF mass ratio of 50, a time of 1 h and a temperature of 140 °C, to obtain a yield of 41.18 %.

Improving Flame Retardancy of Pineapple Leaf Fibers

2020
Pineapple leaf fibers (PALF) are very suitable to act as reinforcing composite matrixes. Nevertheless, PALF is highly susceptible to the risk of fire hazard. Therefore, priority is often being placed in order to improve the fire retardancy of the PALF and its composite products.

Pineapple Leaf Fibers Coated with Polyacrylamide Hydrogel

Applied Mechanics and Materials, 2014
Pineapple leaf fibers (PALF) have several advantages such as low cost, eco-friendly, and high specific strength. However, the brittleness of PALF limits its application. To overcome this limitation of PALF, it is essential to synergize the advantages of PALF with elastic properties of hydrogel.

Developmental toxicity of orally administered pineapple leaf extract in rats

Food and Chemical Toxicology, 2011
The extract of pineapple leaves (EPL) has anti-diabetic and anti-dyslipidemic effects and can be developed into a promising natural medicine. This study was conducted to evaluate EPL's effects on developmental parameters in order to provide evidence of its safety before potential medical use. Five groups were included: a negative control that was given

The Potential of Pineapple Leaf Fibre as an Acoustic Absorber

2019
This study discussed an alternative material known as pineapple leaf fibres (PALF) as a replacement of synthetic fibres in sound absorber production. The samples were fabricated from two different sizes of PALF, with and without binder of different thicknesses and densities to determine their effects on the sound absorption coefficient (SAC).

Thermal properties of pineapple leaf fiber reinforced composites

Materials Science and Engineering: A, 2003
Simultaneous measurment of effective thermal conductivity (λ) and effective thermal diffusivity (κ) of pineapple leaf fiber reinforced phenolformaldehyde (PF) composites have been studied by transient plane source (TPS) technique. The samples of different weight percentage typically (15, 20, 30, 40 and 50%) have been taken.
