Book Description
Natural fiber composites have experienced a renaissance over the last two decades as a response to societal demands for developing eco-friendly, biodegradable and recyclable materials. They are now being extensively used in everyday products as well as in automotive, packaging, sports and the construction industries. These fibers require surface treatments in order to improve their properties and interfacial bonding with polymer matrices, and to reduce their hydrophilic character. These methods can be grouped into three major categories: chemical, physical and biological. Chemical methods use chemical reagents to reduce fibers’ hydrophilic tendency and thus improve compatibility with the matrix. They also expose more reactive groups on the fibre surface to facilitate efficient coupling with the matrix. Physical methods change structural and surface properties of the fiber and thereby influence the interfacial bonding with matrices, without extensively changing the chemical composition of the fibers. They are cleaner and simpler than the chemical methods. Biological methods use biological agents like fungi, enzymes and bacteria to modify the fiber surface properties. These methods are not toxic like chemical methods and are not energy-intensive like physical methods. Surface Treatment Methods of Natural Fibers and their Effects on Biocomposites presents an overview and recent developments of these methods. All the major methods are reviewed, explaining the science and methodology behind each method. The effects of these methods on various properties of fibers and the biocomposites made from these fibers are analyzed in detail. The book will be an essential reference for academic researchers, materials scientists and engineers, postgraduate students and industrial researchers and development scientists and engineers working on natural fibers and biocomposites. Extensive coverage of all the surface modification methods (chemical, physical, biological) of natural fibers and its effect on properties of produced composites The chemical mechanisms which are utilized in surface treatments are discussed in detail and how these affect the interfacial properties and characteristics Systematic and comprehensive review on surface modifications of natural fibres, and explains how the effect of the surface treatment can be characterized and measured, as well as the effect on properties

Book Description
This book is addressed to Master and PhD students as well as researchers from academia and industry. It aims to provide the key definitions to understand the issues related to interface modifications in natural fibre based composites considering the particular supramolecular and micro- structures encountered in plant fibres. A particular emphasis is given to the modification and functionalization strategies of natural fibres and their impact on biocomposites behaviour and properties. Commonly used and newly developed treatment processes are described in view of scaling-up natural fibre treatments for their implementation in industry. Finally, a detailed and comprehensive description of the tools and methodologies developed to investigate and characterize surfaces and interfaces in natural fibre based composites is reviewed and discussed.

Book Description
This book provides a general overview of the importance of fibre-matrix interfacial bonding characteristics in natural fibre-based composites to obtain optimal material properties for a specific application. Composites materials are prepared by combining fibres and polymers to achieve superior materials properties than those of the individual components. Composite materials are used to produce lightweight components with increased stiffness and strength; their properties can also be tailored for any specific applications. The glass fibre reinforced composites dominate 95% of the thermoplastic and thermoset-based composites. However, the natural fibre reinforced composites can give competition to the glass fibres due to their advantages such as biodegradability, low density, low cost, and good mechanical properties. This book looks into biocomposites and its important aspect of optimization of materials’ performance by fine-tuning the fibre-matrix bonding characteristics. The chapters in the book look at different plant fibres such as kenaf, pineapple leaf, jute, date palm, luffa, cotton, hemp, wood, bamboo, flax, and straw and the different approaches to enhance the fibre-matrix interfacial bonding through physical and/or chemical treatment methods. It demonstrates that the nature of fibre-matrix bonding has a significant effect on the properties such as tensile, flexural, impact, inter-laminar shear strength, moisture absorption, thickness swelling, thermal, chemical, damping, creep, and fatigue. Its content appeals to academics, students, researcher, and scientist who are working in the field to produce biodegradable and recyclable materials in the composite industry.

Book Description
One of the major reasons for composite failure is a breakdown of the bond between the reinforcement fibres and the matrix. When this happens, the composite loses strength and fails. By engineering the interface between the natural fibres and the matrix, the properties of the composite can be manipulated to give maximum performance. Interface engineering of natural fibre composites for maximum performance looks at natural (sustainable) fibre composites and the growing trend towards their use as reinforcements in composites.Part one focuses on processing and surface treatments to engineer the interface in natural fibre composites and looks in detail at modifying cellulose fibre surfaces in the manufacture of natural fibre composites, interface tuning through matrix modification and preparation of cellulose nanocomposites. It also looks at the characterisation of fibre surface treatments by infrared and raman spectroscopy and the effects of processing and surface treatment on the interfacial adhesion and mechanical properties of natural fibre composites. Testing interfacial properties in natural fibre composites is the topic of part two which discusses the electrochemical characterisation of the interfacial properties of natural fibres, assesses the mechanical and thermochemical properties and moisture uptake behaviour of natural fibres and studies the fatigue and delamination of natural fibre composites before finishing with a look at Raman spectroscopy and x-ray scattering for assessing the interface in natural fibre compositesWith its distinguished editor and international team of contributors Interface engineering of natural fibre composites for maximum performance is an invaluable resource to composite manufacturers and developers, materials scientists and engineers and anyone involved in designing and formulating composites or in industries that use natural fibre composites.

Book Description
Natural fiber composites are a preferred alternative to conventional composites due to their environment-friendly nature. However, their market share is limited due to: a) limited number and quantities of natural fibers available for composites, b) diversity in fibers structure, c) poor mechanical properties of fibers as well as composites, d) susceptibility to microbial attacks, and e) cellulose degradation temperature around 200 deg C, which hinders the development of natural fiber reinforced thermoplastic composites using thermoforming at high temperatures. A number of researchers have contributed to the solution of the problem of poor mechanical properties and issues related to fabrication during the last decade. This book covers these different solutions. The book is divided into two principal themes: a) structure–property relationship: fibers to composites—it includes the discussion on fibers, their surface modifications, variation in the structure of reinforcement, and approaches for the enhancement of properties. b) Fabrication process of composites—it includes the novel approaches used for the development of natural fiber composites using the commingling technique for thermoplastic composites.
