Synthesis and Characterization of Short Saccaharum Cilliare Fibre Reinforced Polymer Composites

Abstract

This paper deals with the synthesis of shortSaccaharum Cilliarefibre (SC) reinforced Urea-Formaldehyde (UF) matrix based polymer composites. Present work reveals that mechanical properties such as: tensile strength, compressive strength, flexural strength and wear resistance of the UF matrix increase up to 30% fibre loading(in terms of weight) and then decreases for higher loading when fibers are incorporated into the matrix polymer. Morphological and Thermal studies of the matrix, fibre and short fibre reinforced (SF-Rnf) green composites have also been carried out. The results obtained emphasize the applications of these fibres, as potential reinforcing materials in bio based composites.

Influence of Chemical Treatments on Flexural Strength of Areca Fiber Reinforced Epoxy Composites

“…This is because of better fiber distribution in matrix, less fiber fractures and effective transfer of load from matrix to fibers at 60% fiber loading. The observed increase in flexural strength values with chemical modification and as well as with increase in fiber loading up to 60% is in good agreement with the results reported in literature 4,5,14,33 . The decrease in flexural strength values for untreated as well as chemically treated areca/epoxy composites beyond 60% fiber loading is due to poor interfacial adhesion and inefficient stress transfer from matrix to fibers 34 .…”

“…Chemical treatments increased flexural strength due to removal of outer fiber surface, increase in cellulose content and interfacial adhesion. After 30%, the observed decrease is due to poor interfacial bonding resulting in spaces between fiber and matrix generating a weak structure 14 . Hence, surface modifications of natural fibers are one of the most important areas in the field of technical utilization of natural fiber reinforced composites in industrial sector.…”

Acoustic and Mechanical Properties of Polymer Composites Reinforced by Pre-Deformed Palm Fiber

“…Natural fiber composites have been studied and reviewed by a number of researchers (Debasish D., et al(2004) [4], H.P.S. Abdull Khalil, et al(2006) [5], Saira Taj, et al (2007) [6], A. S. Singha and V. K. Thakur (2008) [7], A. S. Singha and V. K. Thakur (2oo9) [8], M. J. Mohd Nor et al (2010) [9] K. Ramanaiah et al (2012) [10]). The mechanical properties and physical properties of natural fibers vary considerably depending on the chemical and structural composition, source, age, fiber type, growth condition and separating techniques of the fiber [5,11].…”

Synthesis and characterization of Cannabis indica fiber reinforced composites

“…Urea-formaldehyde (UF) resin was synthesized by the standard method developed in our Applied Chemistry research laboratory (Singha et al 2007(Singha et al , 2008. Urea and formaldehyde in the ratio 1.0:2.5 were taken by weight, in the reaction kettle, and were mixed with the varying molar ratios of resorcinol (0.5, 1.0, 1.5, 2.0, and 2.5) by weight with the help of a mechanical stirrer.…”

“…In our research laboratory comprehensive research on the utilization of natural fibers in polymer matrix composites had been carried out in the last few years. This research has involved pine needles (Singha et al 2008c,d and2009), Saccharum cilliari (Singha et al 2002(Singha et al , 2007(Singha et al , 2008a, Habiscus sabdariffa (Singha et al2008e), and flax (Kaith et al 2003(Kaith et al , 2004 fibers as the reinforcing fillers in polymer matrix composites.…”
