Effect of Nano-filler on the Manufacturing and Properties of Natural Fiber-based Composites: A Review

Abstract

Natural fiber reinforced polymer composite offers ecological safety towards a sustainable environment. Meanwhile, the deficiency of the poor interfacial bonding between fiber and matrix draws the attention of researchers to be sorted out. The use of inorganic nanofiller is considered as a possible solution to overcome the hurdle nowadays besides strengthening the composite properties. This article thoroughly reviews the use of inorganic nanofillers in natural fiber composites, covering different manufacturing processes and properties. Factors of various manufacturing techniques occupied for composite fabrication are investigated. Moreover, the influences of different nanofillers on mechanical, thermal, chemical, and physical properties of composites are discussed. In addition, Scanning Electron Microscopy (SEM) images of the bio composites are critically reviewed that usually exhibit the interfacial bonding and the fractures of the specimen. Furthermore, application of such natural fiber composites and the future investigation pathway in using inorganic nanofiller in composite are narrated.
