About this Research Topic

Manuscript Submission Deadline 10 November 2022

Recent progress in technology has led to the extensive use of composites for various applications. The adverse effect of these non-biodegradable synthetic composites on the environment has become increasingly alarming. This has led to the rise in environmental awareness across the globe that has compelled researchers to reinstate their interest in the development of natural resource-based composite materials. The increase in environmental awareness has proliferated the usage of the term green and eco-friendly composites which has become an inescapable part of any development plan for almost every developing or developed nation to reduce its environmental footprint for sustainable development. Therefore, researchers are studying the possibility of replacing synthetic fibers such as glass, carbon, etc. with natural ones. The natural resource-based composites find significant applications in the manufacture of products such as protective casings for electronic devices, reinforcements in the building and construction industry, automotive interiors, electromagnetic shielding, and packaging industries where high load-carrying capacity is not required. Natural fiber-based biodegradable composites have also been extensively used for biomedical applications.

The aim of this Research Topic is to study the advancements in the area of natural resource-based composites for various applications. The synthetic materials possess high mechanical or thermal properties, however, drawbacks such as non-biodegradability that promotes adverse environmental hazards has compelled the research community towards eco-friendly alternative counterparts i.e., natural resource-based composites. The use of sustainable and eco-friendly composites has become indispensable in today’s world. Natural fibers offer many advantages such as low density, good biodegradability, and good vibro-acoustic properties. However, to enhance the mechanical strength and biocompatibility of these composites, surface treatments are necessary. Moreover, natural resources are abundant in countries like India, Bangladesh, Indonesia, Malaysia, etc. which can be utilized for the development of biodegradable, eco-friendly and sustainable products. However, the judicious use of these natural resources requires extensive research in the area of natural resource-based composite materials to promote natural resource-based composites as an enduring solution to environmental pollution without compromising the qualities of the products. Comprehensive discussions on the different kinds of natural resource-based composites, fabrications routes, surface modification methods, their biodegradability, characterization techniques and areas of application have been studied in detail.

Research on the processing, surface modification and characterization of natural resource-based composites for various applications are welcome, on the following themes.
1) Natural resource-based composites: Sources
(a) Sustainable resources for the production of carbon fibers
(b) Polylactic acid, Cellulose and biomass-derived natural composites

(b) Thermo-mechanical characterization of sustainable structural composites.
(c) Dielectric and biocompatibility behaviour of biocomposites.
(d) Effect of surface modifications/functionalization on the thermo-mechanical behaviour of natural resource-derived composites.
