Book Description

Composites are now extensively used in applications where outstanding mechanical properties are necessary in combination with weight savings, due to their highly tunable microstructure and mechanical properties. These properties present great potential for part integration, which results in lower manufacturing costs and faster time to market. Composites also have a high level of styling flexibility in terms of deep drawn panel, which goes beyond what can be achieved with metal stampings. The so-called multifunctional or smart composites provide significant benefits to the vehicles as compared to the traditional materials that only have monotonic properties. CAE Design and Failure Analysis of Automotive Composites focuses on the latest use of CAE (Computer-Aided Engineering) methods in design and failure analysis of composite materials and structures, beginning with a brief introduction to the design and failure analysis of composite materials, and then presenting some recent, innovative CAE design examples of composite structures by engineers from major CAE developers and automobile OEMs and suppliers. This title brings together 12 SAE technical papers, carefully selected by the editors covering three main areas of expertise: • Design and Failure Analysis of Composites: Static Loading • Design and Failure Analysis of Composites: Dynamic and Impact Loading • Design and Failure Analysis of Composites: Blast Loading

Book Description

With their high specific strength and stiffness, composites have the potential to significantly lower the vehicle weight, which can have a dramatic effect on improving fuel efficiency and reducing greenhouse gas emissions. For the past decade or so, composites have been experiencing several transitions, including the transition from micro-scale reinforcement fillers to nano-scale reinforcement fillers, resulting in the nanocomposite. The effectiveness of the nano-sized fillers in composites can be explained by one of their unique geometric properties: the length-to-thickness aspect ratio. Therefore, nano-sized fillers have exceptionally higher reinforcing efficiency than the conventional, large fillers. The effectiveness of the nano-sized fillers in composites is also due to their large surface area and surface energy. This book consists of a collection of technical papers selected from the automotive composites and other relevant sessions that the editors have organized for the SAE World Congress over the past decade. It begins with a section on the perspectives of nanocomposites in the automotive industry, with of three excellent papers given by experts from the industry and academia. Following, it brings to the reader in-depth information on the three major nanocomposites categories: o Nano-fiber reinforced composites o Nano-platelet reinforced composites o Nano-particle reinforced composites

Book Description

The automotive sector has taken a keen interest in lightweighting as new required performance standards for fuel economy come into place. This strategy includes parts consolidation, design optimization, and material substitution, with sustainable polymers playing a major role in reducing a vehicle's weight. Sustainable polymers are largely biodegradable, biocompatible, and sourced from renewable plant and agricultural stocks. A facile way to enhance their properties, so they can indeed replace the ones made from fossil fuels, is by reinforcing them with fibers to make composites. Natural fibers are gaining more acceptance in the industry due to their renewable nature, low cost, low density, low energy consumption, high specific strength and stiffness, CO2 sequestration potential, biodegradability, and less wear imposed on machinery. Biocomposites then become a very feasible way to help address the fuel consumption challenge ahead of us. This book, entitled Biocomposites in Automotive Applications, is segmented into three sections and includes eleven hand-picked technical papers covering: * Processing and characterization of biocomposites * Automotive applications of biocomposites * A perspective on automotive sustainability It is a must read for those interested in the growing importance of composites used in automotive applications and their impact on sustainable mobility.

Book Description

The synthetic counterparts of natural polymeric materials are now finding applications as light weight, mechanically strong, and environmentally stable sheets, fibers, films, adhesives, paints, and foams have replaced most of the commodity and structural materials. The systematic research on the preparation, characterization, and utilization of plastics resulted in creation of polymers often containing a set of several desirable properties in a single polymer. The polymers have established their place in engineering applications as well. Although the bulk of plastics production focuses on relatively simple commodity polymers, the proportion of specially designed and tailor-made plastics for specific and sophisticated applications is also increasing at a great pace. The specialty plastics, as well as their use in specific and sophisticated applications, are the key to the continued scientific growth and technological advances in the new millennium. This book thoroughly covers today's rapidly growing field of specialty polymers and their applications in more sophisticated and specialized areas. It gives the most recent in-depth knowledge and extremely comprehensive details of the chemistry, physics, material science, technology, and device applications of specialty polymers. This comprehensive book containing 16 chapters is the result of the untiring efforts of 35 most renowned experts from the national and international scientific community. This book is thought-provoking to the researchers working in the fields of chemistry, biochemistry, biotechnology, medicine, polymer chemistry, semiconductor physics, material science, electrochemistry, biology, electronics, photonics, material science, solid state physics, nanotechnology, electrical and electronics engineering, optical engineering, device engineering, data storage, etc.
