Thermoset Composites

This report reviewed some of the resin systems used for these lightc099 applications, the reinforcements employed and the techniques developed and used to convert them efficiently and as economically as possible into components and structures.

Characterization, design, specific properties and applications of thermoset composites are reported. These composites are presently in high demand because they can be shaped into many-sided segments and structures, and can have a great variety of densities and special physical and mechanical properties. The research reported includes: Energy absorption of fiber reinforced composites; automotive crashworthiness; lignocellulosic composites; hybrid bast fiber reinforced composites; nano-carbon/polymer composites; electromagnetic shielding; structural mechanical applications; electromagnetic field emission applications, conductive composites; epoxy composites for structural purposes; tribological performance of polymeric composites.

This book bridges the technology and business aspects of thermosets, providing a practical guide designed for engineers working in real-world industrial settings. The author explores the criteria for material selection, provides information on material properties for each family of thermosets, and discusses the various processing options for each material type. He explains advantages and disadvantages of using thermosets and composites in comparison to competing materials and assesses cost aspects, enabling the reader to balance out technical and economic constraints when choosing a thermoset and processing technology for a given application. This second edition contains a new section on composites solutions for practical problems, gathering information on trends contributing to the breakthrough of composites in various sectors. Other new sections on specific crosslinking processes, processing trends, machinery and equipment manufacturers, applications, bio-sourced thermosets and natural fibers, and recycling of thermosets and composites are included. Case studies are provided, illustrating many design and production challenges. Furthermore, new market data and information about health and safety will be added. All data is fully updated throughout, with pricing in USD and EUR, and both ASTM (North American) and European standards. Thermosets and Thermoset Composites, Second Edition is the only book that gives in-depth coverage of a wide range of subject matters and markets, yet in brevity and concision in a single volume, avoiding the need of consulting a series of other specialized books. By providing the knowledge necessary for selecting a fabrication process, thermoset material and methods for determining the all important cost of thermoset parts this new edition is an invaluable decision-making aid and reference work for practitioners in a field with growing importance. Combining materials data, information on processing techniques, and economic aspects, Biron provides a unique end-to-end approach to the selection and use of materials in the plastics industry and related sectors New material on bio-sourced thermosets, natural fibers, and recycling of thermosets Concise and easy-to-use source of information and decision-making aid

Abstract: Four fiber/resin systems were compared for resistance to damage and damage tolerance. One toughened epoxy and three toughened bismaleimide (BMI) resins were used, all with IM7 carbon fiber reinforcement. A statistical design of experiments technique was used to evaluate the effects of impact energy, specimen thickness, and tup diameter on the damage area as computed by C-scans, and residual compression-after-impact (CAI) strength. Results showed that two of the BMI systems sustained relatively large damage zones yet had an excellent retention of CAI strength.

This second edition has been compiled to take account the continued expansion of the composites industry. Additional entriesout of part two allows more property tabulation and more descriptive entries for resins.

• A succinct source of information for designers and manufacturers. • A decision-making tool for those who need a quick and pragmatic account of thermosets and composites. • A synoptic account of the techno-economics and properties of all the commonly-used thermosets and composites. Designers and manufacturers using thermosets and composites, or those intending to do so, often need a succinct source of information on the economics and properties of these materials. This book provides a synoptic approach. It covers the economic importance of thermosets and composites, a comparison of the properties of the various thermoset categories, monographs on the nine principal families of thermosets, polymer composites and emergent materials and processes. Will enable readers to make informed decisions leading to well designed and made products.
