This book was released on 2019-09-16 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: From last few decades’ composite materials, ceramics and plastics has made a mark in the field of materials. Applications of these materials in engineering arespecially attributed to their low specific weight and comparatively high strength. Applications of composite materials vary from the basic daily needs to sophisticated luxury applications. The demand of natural fiber in the composite materials has been increased owing to low density, low cost and biodegradable properties of natural fiber.But at the same time the natural fibers has certain disadvantages viz. they are hydrophilic in nature due to which there is poor incompatibility of natural fiber with the matrix. This intensity of this disadvantage can be reduced with the help of chemical treatment of natural fibers. Natural fiber has tendency of water absorption, which can also be reduced with chemical treatment. There are number of factors which affect the properties of natural fiber reinforced composite viz. fabrication method, environment condition during fabrication, fiber and its quantity, matrix material. Any slight modification in the above said variables leads to change in the properties of the final composite material. In the present work, the tensile and flexural properties of natural fiber (abaca fiber) reinforced TPU composites have been investigated. The content of natural fiber in composites has been varied from 0 to 30 wt%. The reinforced fibers were chemically treated with NaOH followed by treatment with maleic anhydride in acetone, prior to fabricating of samples by injection moulding. It is observed that the composite containing 10 wt% of abaca fiber has highest tensile strength among all the composites fabricated for this study, whereas the tensile strength of pure TPU sample has maximum among all the samples fabricated during this research work.Maximum flexural strength is observed ofthe composite containing 30 wt% of abaca fiber.SEM examinations of the fractured surface reveal that primary failure mechanisms in composite as fiber fracture and fiber pull-out.

Available in PDF, EPUB and Kindle. Book excerpt: Composites are the most promising material available in the twenty-first century. Composites reinforced with synthetic or natural fibers are becoming extremely prevalent as the demand for lightweight materials with high strength for specific applications grows. Fiber-reinforced polymer composite has a high strength-to-weight ratio and excellent properties, such as high durability, stiffness, damping property, flexural strength, and resistance to corrosion, wear, impact, and fire. Various properties of composite materials have led to applications in construction, aerospace, automobile, biomedical, marine, and many other industries. Because their constituent elements and manufacturing techniques primarily determine the performance of composite materials, the functional properties of various fibers available worldwide, their classifications, and the manufacturing techniques used to fabricate the composite materials must be investigated.

Available in PDF, EPUB and Kindle. Book excerpt: Biomass obtained from agricultural residues or forest can be used to produce different materials and bioenergy required in a modern society. As compared to other resources available, biomass is one of the most common and widespread resources in the world. Thus, biomass has the potential to provide a renewable energy source, both locally and across large areas of the world. It is estimated that the total investment in the biomass sector between 2008 and 2021 will reach the large sum of $104 billion. Presently bioenergy is the most important renewable energy option and will remain so the near and medium-term future. Previously several countries try to explore the utilization of biomass in bioenergy and composite sector. Biomass has the potential to become the world’s largest and most sustainable energy source and will be very much in demand. Bioenergy is based on resources that can be utilized on a sustainable basis all around the world and can thus serve as an effective option for the provision of energy services. In addition, the benefits accrued go beyond energy provision, creating unique opportunities for regional development. The present book will provide an up-to-date account of non-wood, forest residues, agricultural biomass (natural fibers), and energy crops together with processing, properties, and its applications to ensure biomass utilization and reuse. All aspects of biomass and bioenergy and their properties and applications will be critically re-examined. The book consists of three sections, presenting Non wood and forest products from forestry, arboriculture activities or from wood processing, agricultural biomass (natural fibers) from agricultural harvesting or processing and finally energy crops: high yield crops and grasses grown especially for energy production.​

Available in PDF, EPUB and Kindle. Book excerpt: Composites are used in a wide range of applications, from electronics to the aeronautical industry. The excellent mechanical properties and low-specific weight of composites are the basis of many structural applications. Despite the progress achieved, there are significant obstacles to the generalisation of structural applications of composites, mainly due to their high cost and complex mechanical behaviour. In fact, there is currently insufficient knowledge regarding the mechanical properties and failure mechanisms of composites made from renewable and sustainable materials. This book focuses on composites from natural and renewable resources, including the enhancement of their properties with additives such as biodegradable nanomaterials, their mechanical characterisation, tailoring of properties for specific applications and their processing.
