Characterization of natural fiber and composites – A review

Abstract

The natural fiber-reinforced polymer composite materials offered extensive range of properties which are suitable for large number of engineering application. The natural fibers have been abundantly available in the world. It has unique properties compared to synthetic fiber and reduces the plastic usage. This article reports the extraction process of natural fibers, characterization of natural fibers, and preparation of natural fiber-reinforced composites. The mechanical properties such as tensile, flexural, impact, and dynamic properties as well as thermal and machinability properties of the composites with and without chemically treated fibers were reported. The water absorption capability of the composites and its effect on mechanical properties were also reported.

A Study on Chemical Composition, Physical, Tensile, Morphological, and Thermal Properties of Roselle Fibre: Effect of Fibre Maturity

“…However, the changes are dependent with each other; a decrease of hemicelluloses content is accompanied by an increase of lignin and vice versa. Hemicelluloses constitute a class of polysaccharide polymers in which the degree of polymerization and orientation are less than cellulose (Sathishkumar et al 2013). They normally occupy the space in between cellulose and lignin.…”

“…Approximately 5 mg of roselle fibre was used to evaluate the thermal behavior. Generally, there are 4 phases on the thermal degradation of natural fibre (Rosa et al 2009;Shahzad 2013;Sathishkumar et al 2013). Figure 10 indicates the curves for weight loss and differential weight loss for roselle fibres as the temperature rises.…”

“…Some recent studies on chemical composition, mechanical, thermal, andmorphological characteristicshave been carried out on natural fibres (Rowell et al 2000;Munawar et al 2006;Rosa et al 2009;Ishak et al 2011;Sathishkumar et al 2013;Mwasiagi et al 2014;Yusriah et al 2014). Ishak et al (2011) have conducted a characterization on the thermal and tensile properties of sugar palm fibres.…”

Characterisation of Textile and Oleaginous Flax Fibrous and Shives Material as Potential Reinforcement for Polymer Composites

“…e lignocellulosic brous material compounds containing cellulose, hemicelluloses and lignin consist of oxygen containing functional groups (ester, ketone and alcohol), alkenes and aromatic groups [1,11,25,26,29,30]. e Fourier transform infrared (FT-IR) spectra of ax bres separated into four length groups and shives are shown in Figures 9 and 10.…”

“…cellulose, hemicellulose and lignin) is known to vary among plant bre types. e presence of pectin and waxes can lead to the formation of an ine ective interface between the bre and polymer matrix with consequent problems such as debonding and voids in resulting composites [1,[9][10][11]. e chemical composition of textile and oleaginous ax bres is shown in Table 1.…”
