Book Description
The reinforcement of materials such as mud and clay by hair, straw and vegetable fibres has been long established in man's history, enabling him to improve his buildings and extend his engineering abilities. With the advent of modern synthetic polymers it was rapidly realised that the addition of fibres, flakes and particulate materials to polymer matrices could improve mechanical properties significantly. Fibres and flakes are the most effective and have enabled several polymers with limited properties to compete with long-established metallic materials, reSUlting in cost, weight and processing economies. This is increasingly apparent in the selection of materials for aerospace and road vehicle applications as well as in a multitude of domestic products. Reinforced plastics, both thermosets and thermoplastics, are used in increasingly harsh environments involving elevated temperatures and aggressive conditions. Fibre reinforcement of thermoplastics dominates, and a pattern of increasing replacement of fibre reinforced thermosets by reinforced thermoplastics is emerging. This trend is encouraged by the development of continuous fibre reinforced grades of the newer high-temperature engineering thermoplastics such as polyether ether ketone. The first part of this book reviews the mechanical properties and theories of short fibre reinforcement. The principal reinforcements are reviewed and a separate chapter is devoted to the uses of natural fibres as reinforcements for thermoplastics. This is an interesting and commercially important area, especially for Third World countries v vi Preface where these fibres are grown but are facing severe competition from synthetic fibres in traditional applications such as ropes and matting.

Book Description
The proper choice of technology is a complex decision, particularly for developing countries, as it depends not only on local needs and conditions but also, importantly, on the national political context and, increasingly, on the international environment. This technological choice carries with it the genetic code of the nation's future development. Many developing countries which lack the needed infrastructure do not have real options; others with a reservoir of scientific and engineering skills and explicit SIT strategies, can indeed choose between alternatives. Turning to the technologies themselves, these cover a wide spectrum: traditional technologies that are low-cost, low-energy and often better suited to meet basic needs; more sophisticated technologies which are highly knowledge-intensive and require large capital outlays for research, product design and manufacturing; and still others which depend upon a blending of modern technology with traditional methods to create products and processes more suited to local needs. Even within the group of advanced technologies, there is considerable differentiation, and those at the lower end of the product cycle are clearly within reach by the newly industri alizing countries.

Polypropylene Handbook

Languages : en
Pages : 648
Book Description
This book extensively reviews Polypropylene (PP), the second most widely produced thermoplastic material, having been produced for over 60 years. Its synthesis, processing and application are still accompanied by vigorous R&D developments because the properties of PP are at the borderline between those of commodity and engineering thermoplastics. Readers are introduced to various tacticities and polymorphs of PP, and their effects on structural properties. Further, the book addresses the control of optical properties using nucleants, provides strategies for overcoming the limited cold/impact resistance of PP, examines in detail the effects of recycling, and presents guidelines for the property modification of PPs through foaming, filling and reinforcing with respect to target applications. Special attention is paid to descriptions and models of properties as a function of morphological variables. Last but not least, the book suggests potential practical applications of PP-based systems, especially in the packaging, appliances, building/construction, textile and automotive sectors. Each chapter, written by internationally respected scientists, reflects the current state-of-art in the respective field and offers a vital source of information for students, researchers and engineers interested in the morphology, properties, testing and modeling of PP and PP-based systems. The content is indispensable to the appropriate application of PPs and related composites.
Direct Processing of Long Fiber Reinforced Thermoplastic Composites and their Mechanical Behavior under Static and Dynamic Load

Book Description
The mechanical behavior of fiber reinforced thermoplastic composites is mainly influenced by fiber length. However, fiber length is strongly reduced during processing. For this reason direct processing techniques are increasingly applied in order to avoid fiber fracture and thus to generate composites with long fibers. This work investigates the influence of fiber length especially on fatigue behavior of thermoplastic composites. The processing influences on fiber length of composites during injection molding compounding are thereby analyzed and quantified. It is thus shown how to directly influence fiber length in the composite.
