A Review on Chemical and Mechanical Properties of Natural Fiber Reinforced Polymer Composites

Abstract

This review paper examines the chemical and mechanical properties of natural fiber reinforced polymer bonded composites and the processing techniques are compared for the reinforced composite materials. The chemical and mechanical properties of the different natural fibers composites were compared. Present days natural fibers are attracting many scholars and researchers due to its cost and largely available in nature also processing of these fibers is not hard in comparison to the conventional fiber's production. Also, Environmental awareness and a growing concern with the greenhouse effect have triggered the construction, automotive, and packing industries to watch out for ecofriendly materials that can replace conventional synthetic polymeric fiber's. Natural fibers seem to be a good alternate because they are readily available in fibrous form and can be extracted from herb leaves at very low costs. By these reasons the natural fibers are trusted over the regular fibers.

Karakterisasi Mekanik Komposit Matriks Polipropilena High Impact Dengan Serat Alam Acak Dengan Metode Hand Lay Up Untuk Komponen Automotive

“…Pada penelitian umunya telah, dilakukan studi sifat tarik dan sifat impak dari komposit PPHI berpenguat serat rami, dimana PPHI dimanfaatkan sebagai bahan pengikat dan serat rami berfungsi sebagai bahan penguat dengan berbagai fraksi volume, dan fraksi volume 10 % PPHI dan penambahan serat rami meshing dibawah 1200 dapat meningkatkan kekuatan tarik PPHI sebesar 21%dan meningkatkan harga impak PPHI sebesar 15.5%. [5] Selain serat rami dilihat dari rata-rata hasil produksi serat di Indonesia bahwa serat nanas memilki nilai yang paling tinggi [4], dan bila ditinjau dari sifat mekanik yakni modulus elastisitasnya lebih baik dibandingkan dengan rami [6], oleh karena itu dilakukan studi sifat mekanik menggunakan pengujian tarik, bending dan Impak untuk komposit baerpenguat serat alam rami dan nanas dengan variasi meshing 120/170, 170/200 dan dibawah 200 akan dicampur dengan matrik PPHI fraksi volume 10 % sehingga akan mendapatkan serat alam dengan meshing yang optimal.…”

Processing and Mechanical Behaviour of Bamboo Fiber Reinforced Polymer Composite Materials

“…Thompson [8] produced a hair-based composite material by controlling a majority of trim lengths of hair to shape a web or tangle of hair, and consolidating said web or tangle of hair with an auxiliary added substance to frame said composite material. Jain et al [9] examined on hair fiber fortified concrete and presumed that there is colossal augmentation in properties of cement as per the rates of hairs by weight of in concrete.…”

Electrical conductivity of the graphene nanoplatelets coated natural and synthetic fibres using electrophoretic deposition technique

“…The NF based composites have seen increased popularity in the past few years with a dramatic increase in the composite market due to their environment friendly attributes [3]. Considering the fact that the disposal and recycling process of synthetic fibres such as GF and CF reinforced polymer composites could result in environmental concerns, NF could offer solutions for these issues, thanks to their recyclability, biodegradability and renewability [3][4][5][6][7][8][9][10]. In addition, they are abundant and cost-effective reinforcing materials with attractive properties, such as low density, high specific strength to stiffness ratio, high toughness, low energy utilisation during the fabrication process, low abrasiveness, and neutrality to CO 2 [3][4][5][6][7][8][9][10].…”
