Structural Applications

Natural fibers have been used to reinforce materials in many composite structures. Many types of natural fibers have been investigated including flax, hemp, ramie, sisal, abaca, banana etc., due to the advantage that they are light weight, renewable resources and have marketing appeal. These agricultural wastes can also be used to prepare fiber reinforced polymer hybrid composites in various combinations for commercial use. Application of composite materials in structural applications has presented the need for the engineering analysis. The present work focuses on the fabrication of polymer matrix composites by using natural fibers like banana and cotton which are abundant in nature and analysing the effect of mechanical properties of the composites on different surface treatments on the fabric. The effect of various surface treatments (NaOH, SLS, KMnO4) on the mechanical properties namely tensile, flexural and impact was analyzed and are discussed in this project. Analysing the material characteristics of the compression moulded composites; their results were measured on sections of the material to make use of the natural fiber reinforced polymer composite material for automotive seat shell manufacturing.

This paper is a review on mechanical characteristics of natural fibers reinforced elastomers (both thermoplastics and thermosets). Increasing environmental concerns and reduction of petroleum resources attracts researchers attention to new green eco-friendly materials. To solve these environmental related issues, cellulosic fibers are used as reinforcement in composite materials. These days natural fibers are at the center of attention as a replacement for synthetic fibers like glass, carbon, and aramid fibers due to their low cost, satisfactory mechanical properties, high specific strength, renewable resources usage and biodegradability. The hydrophilic property of natural fibers decreases their compatibility with the elastomeric matrix during composite fabrication leading to the poor fiber-matrix adhesion. This causes low mechanical properties which is one of the disadvantages of green composites. Many researches have been done modifying fiber surface to enhance interfacial adhesion between filler particles and elastomeric matrix, as well as their dispersion in the matrix, which can significantly affect mechanical properties of the composites. Different chemical and physical treatments are applied to improve fiber/matrix interlocking.

Industry Applications

The focus on high-strength and functional natural fiber-based composite materials is growing as interest in developing eco-friendly plastics and sustainable materials increases. An eco-friendly fibrous composite with excellent mechanical properties was prepared by applying the bamboo-derived nano and microfiber multiscale hybridization phenomenon. As a result, the cellulose nanofibers simultaneously coated the micro-bamboo fiber surface and adhered between them. The multiscale hybrid phenomenon implemented between bamboo nano and microfibers improved the tensile strength, elongation, Young’s modulus, and toughness of the fibrous composite. The enhancement of the fibrous preform mechanical properties also affected the reinforcement of biodegradable fiber-reinforced plastic (FRP). This eco-friendly nano/micro fibrous preform can be extensively utilized in reinforced preforms for FRPs and other green plastic industry applications.

Development of new natural fiber composite for a good characteristic is the focus of many studies, because of their cellulose contents make their properties more potential. However, the main challenge in the research on natural fiber/ polymer composites is their poor compatibility. Based on that, the comparison study by chemical treatment of sodium hydroxide (NaOH) method and adding wax has been explored in two different processes to improve the compatibility of the natural fiber surface. The sodium hydroxide (NaOH) treated sugarcane bagasse (SCB) and coconut coir wax (CCW) in low density polyethylene (LDPE) as a reinforced matrix in fact, will enhance the mechanical properties of the resulting composites. In this study, four different compositions of (90/2, 90/4, 90/6, 90/8), with additional of 2% of NaOH and 2-8 % wax with sugarcane bagasse (SCB) / coconut coir respectively were tested. The specimens were analyzed by different techniques such as tensile test, hardness test, impact test and scanning electron microscopy (SEM) according to ASTM standard. This research has shown that the presence of NaOH indicates higher tensile strength and impact strength compared to coconut coir wax (CCW). While for the young modulus and hardness test value shows coconut coir wax (CCW) has increased and improved. The morphological analysis was conducted to determine the effects of natural fiber bonding between the matrix materials for broken specimens after mechanical testing.
