Improvement of Physical, Mechanical and Thermal Properties of Okra Fiber/Polypropylene Composites by UV Radiation

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 ...

Characteristics ofAbelmoschus esculentus(Indian okra) fiber varieties

Emerging Materials Research, 2023
Okra 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.

Comparative Study of Jute, Okra and Pineapple Leaf Fiber Reinforced Polypropylene Based Composite

Advanced Materials Research, 2019
In 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

Heterosis in yield, fiber quality, and photosynthesis of okra leaf oriented hybrid cotton (Gossypium hirsutum L.)

Euphytica, 2008
Leaf shape is an important factor affecting canopy structure, photosynthetic characteristics, and yield. Introducing okra leaf shape is considered an important strategy in cotton heterosis breeding. The objective of the study was to evaluate the heterosis in okra leaf cotton hybrid F1s, which were developed by crossing two sterile near isolines and ...
