A Review on Potential Uses and Characterization of Okra Fiber Reinforced Polymer Composites

Haydar U. Zaman, Ruhul A. Khan

Abstract

The environment, ecology, and new rules from the government agencies are major concerns in the quick-paced society. As a result, scientists and researchers are searching for natural fiber reinforced composites that are biodegradable and renewable. Natural fibers have undeniable advantages over synthetic fibers, including low density, equivalent strength, non-toxicity, low cost, and minimal waste disposal issues. The possible uses of natural fibers have been thoroughly investigated by researchers. But in this decade, fibers like okra, banana, coir, jute, bagasse, vetiver, calotropis gigantea, and sisal have become more significant. One of the many sources of natural fibers is the okra bahmia (Abelmoschus esculentus) plant. After harvesting the vegetables, a sizable amount of okra plant stem is annually left on the field without being properly utilized. However, this okra plant biomass is a cost-effective, low-density, renewable source that may be used to make bast fibers and other industrially useful eco-friendly materials. Okra fibers are derived from the steam of the okra tree, which is regarded as waste after the fruit harvest, and are a native of tropical Asia. Okra fibers have significantly improved the mechanical, chemical, and physical characteristics of polymer composites when used as a reinforcing material. The current work provides a thorough analysis of okra fiber reinforced composites and their possible uses. In this article, a number of factors that affect the performance of okra fiber reinforced polymer composites are discussed, including fiber length, orientation, and configuration, moisture content, and surface treatments.
