With an internationally recognized team of contributors, Green Composites examines fibre reinforced polymer composite production and explains how environmental footprints can be diminished at every stage of the life cycle. The introductory chapters examine why green composites should be considered. The book then discusses properties of cellulose and wood. It examines recyclable synthetic fibre-thermoplastic composites as alternatives, then covers polymers derived from natural sources. The text details the factors that influence properties, and considers clean processing, applications, recycling, degradation, and reprocessing. The book is essential for government agricultural departments, automotive companies, and others devoted to eco-friendly materials and production.

Discusses the latest results in academia and industry on green composites. Existing machinability problems like low processability and reduction of the ductility are addressed and discussed in relation to use of adhesion promoters, additives or chemical modification of the filler to overcome these problems. Recent industrial efforts to minimize the environmental impact, e.g. biodegradable polymer matrix, renewable sources complete the approach.

Green composites can be prepared by conventional blending wheat gluten (WG) and other organic or inorganic components using conventional plastic processing equipments followed by thermo-moulding of the mixture at elevated temperatures to crosslinking the matrix. In recent years, great attention has been dedicated to the exploitation of natural fibres as reinforcement for plastics, replacing fibres synthetic materials. This book examines the methods for surface modification, which can be physical or chemical, according to superficial modification approach of the fibre. This book also gives a survey about the chemical composition, various mechanical processes for the separation of flax fibre, mechanical properties, physical and chemical treatment methods that improve the flax fibre matrix adhesion, their results and special effects on the various properties of composites. The authors also investigated the preparation and characterisation of Mater-Bi/wood flour green composites. The investigation was completed by performing biodegradation tests which allowed assessing the actual biodegradability of the prepared green composites. Other chapters in this book examine the effects of accelerated exposure to seawater on the flexural and impact properties of composites. Densified wood, which can be effectively used as raw material in the production of wood-base green composites, is discussed as well.

Global awareness of environmental issues has resulted in the emergence of economically and environmentally friendly bio-based materials free from the traditional side effects of synthetics. This book delivers an overview of the advancements made in the development of natural biorenewable resources-based materials, including processing methods and potential applications in green composites. Biorenewable polymers are a special class of natural material found in nature, such as natural fibers, wheat straw, rice husk, and saw dust. In addition to offering renewable feedstocks, natural biorenewable materials are compostable, recyclable, edible, and more energy efficient to process than plastic. Green Composites from Natural Resources covers various kinds of cellulosic biofibers, such as: hemp fibers jute saccaharum cilliare fibers pine needles grewia optiva fibers sisal fibers eulaliopsis binata flax fibers coconut fibers eulaliopsis binata baggase fibers rice husk saw dust wood flour straw With scopes for the utilization of natural resources-based materials as potential replacements for traditional petroleum feedstocks on the rise, more scientists and researchers are exploring new composite materials based on biorenewable resources. This book provides information on more eco-friendly and sustainable alternatives to synthetic polymers and discusses the present state and growing utility of green materials from natural resources.

Most composites, particularly those made using thermoset resins, cannot be recycled or reused. As a result, most of them end up in landfills at the end of their useful life which is neither sustainable nor environment-friendly. Various laws enacted by Governments around the world and heightened global awareness about sustainability and global warming is changing this situation. Significant research is being conducted in developing and utilizing sustainable fibers and resins, mostly derived from plant, to fabricate ‘Green’ composites. The significant progress in the past 20 or so years in this field has led to the development of green composites with high strength or so called Advanced Green Composites. More interestingly, green composites have also acquired various different properties such as fire resistance, transparency, barrier to gases and others. The term ‘advanced’ which only included high strength and stiffness now includes all these special properties. The world is on the cusp of a major change, and once fully developed, such composites could be used in applications ranging from automobiles to sporting goods, from circuit boards to housing and from furniture to packaging. This book, by presenting the state-of-the-art developments in many aspects of advanced green composites adds significantly to the knowledge base that is critical for their success of expanding their use in applications never seen before. The chapters are written by world’s leading researchers and present in-depth information in a simple way. This provides readers and researchers the latest developments in the field of ‘Green’ resins (with ways of strengthening them), High Strength Green Fibers (including micro and nano-cellulose fibrils/fibers) and Green Composites in the first few chapters. The introductory chapter summarizes the consequences of using conventional, petroleum-based materials and the need for green composites as well as the progress being made in this field. After that the book delves in to Advanced Green Composites in a broader sense and includes chapters on High Strength Green Composites, Self-healing Green Composites, Transparent Green Composites, All-cellulose composites, Toughened Green Composites, Green Biofoams, Bioinspired Shape Memory Composites, etc. The chapters are written by the experts who are highly respected in their fields.

Natural fibers and their composites have a long and important place in the history of human creativity and industry. Increasing consumer interest in "green" products made with sustainable materials, along with the rising cost of petroleum - the basic ingredient of synthetic fibers - have once again brought natural fibers and their composites to the fore. The renewed interest in natural fibers is only a few decades old. Thus, the pioneering work of current researchers in this new era of natural fiber composites will help to illuminate the path for future researchers as they explore new potentialities for natural fibers. Sabu Thomas and Laly Pothen, themselves leaders in the field, bring together cutting edge research by eminent scientists in Natural Fiber Reinforced Composites. Covering the latest research trends such as nano technology, the book will be a valuable resource for the natural fiber composite researcher.

Abstract: Due to dwindling reserves of petroleum sources and their non-biodegradability, researchers are looking into alternatives for synthetic fiber and resin system. Some of the techniques used to improve the performance of natural composites are successful, they are still below the performance of synthetic fiber. In this paper we are going to look into some of the commercially used natural fibers, natural resins, their mechanical properties and some of the techniques used for fiber strengthening. Chemical treatment and mechanical loading methods are used to improve the strength of the natural fibers. The main advantage of using natural fiber and resin system is it is cheaper than synthetic composites, bio-degradable, abundantly available. Natural Fiber-reinforced polymer matrix composites have gained commercial success in the semi structural and structural applications such as aircraft, automobiles, sporting goods, electronics, and appliances are quite dependent on natural fiber-reinforced plastics. By using long, aligned natural fibers in conjunction with naturally derived resins, 100% bio-based composites with improved mechanical properties can be achieved and can potentially be employed for more structural purposes.
