Enhancement of Thermo-mechanical Properties of Okra Fiber by Photografting Technique
Journal of The Institution of Engineers (India): Series E, 2021In this study, okra fibers were chemically modified with three different monomers such as ethylene glycol dimethacrylate (EGDMA), 2-hydroxyethyl methacrylate (HEMA) and methyl methacrylate (MMA) solutions in the presence of methanol (MeOH) and photoinitiator (Irgacure-500) under ultraviolet (UV) radiation with a view to improve thermo-mechanical ...

Surface modification of okra bast fiber and its physico-chemical characteristics
Fibers and Polymers, 2009The effect of chemical treatment i.e. bleaching, alkalization and graft copolymerization on the morphology changes of okra bast fiber has been investigated by means of infrared spectroscopy (IR), scanning electron microscopy (SEM), water absorption and tensile properties measurements.

Characteristics ofAbelmoschus esculentus(Indian okra) fiber varieties
Emerging Materials Research, 2023Okra fiber is the natural cellulosic bast fiber extracted from the bark of the Abelmoschus esculentus plant stem. India is the largest producer of okra for the cultivation of ‘okra fruit’. After the okra plant is harvested in the field, the okra fruit is collected as a vegetable, and the okra plant is thrown out as agricultural waste.

Journal of the Institution of Engineers (India): Series E, 2019
In this study, polypropylene (PP) composites (50% fiber by weight) were prepared by reinforcing lignocellulosic okra fiber using compression molding technique. In order to improve the mechanical properties of the composites, virgin okra fiber and PP sheet were exposed to different intensities of UV radiation (25–200 UV dose) and found significant ...

, 2017 The cultivation of conventional fiber plants (cotton, flax, etc.) is in risk as more arable land is needed to be allocated for edible plant species to feed growing world’s population. In order to overcome this problem, agricultural residues may be used as an alternative source of natural fibers.

Cellulose nanocrystals extracted from okra fibers in PVA nanocomposites
Journal of Applied Polymer Science, 2012AbstractCellulose nanocrystals (CNC) were extracted from okra bahmia (Abelmoschus Esculentus) bast fibers and inserted in different tenors (1, 2, 5, and 10 wt %) as the reinforcement of a poly(vinyl alcohol) (PVA) matrix. The extraction of cellulose was carried out in a two‐step procedure: the first chemical treatment led to the production of ...

Comparative Study of Jute, Okra and Pineapple Leaf Fiber Reinforced Polypropylene Based Composite
Advanced Materials Research, 2019In this experimental studies, three types of fabric such as Jute, Okra and Pineapple Leaf Fiber (PALF) were selected and matrix material such as polypropylene (PP) was selected to manufacture composites. Jute/PP, Okra/PP, and PALF/PP based composites were prepared successfully by a conventional compression molding technique. The objective of this study

Effect of Chemical Treatment on the Mechanical Properties of Okra-Fiber-Reinforced Epoxy Composites
Lecture Notes on Multidisciplinary Industrial Engineering, 2019The aim of this paper is to investigate chemical modification and mechanical characterization of okra fiber reinforced with epoxy LY556 as matrix material using hand layup technique. Composites are fabricated with different wt% of fibers as reinforcement and pre-calculated weight of the resin.
