Book Description
The selection and application of engineered materials is an integrated process that requires an understanding of the interaction between materials properties, manufacturing characteristics, design considerations, and the total life cycle of the product. This reference book on engineering plastics provides practical and comprehensive coverage on how the performance of plastics is characterized during design, property testing, and failure analysis. The fundamental structure and properties of plastics are reviewed for general reference, and detailed articles describe the important design factors, properties, and failure mechanisms of plastics. The effects of composition, processing, and structure are detailed in articles on the physical, chemical, thermal, and mechanical properties. Other articles cover failure mechanisms such as: crazing and fracture; impact loading; fatigue failure; wear failures, moisture related failure; organic chemical related failure; photolytic degradation; and microbial degradation. Characterization of plastics in failure analysis is described with additional articles on analysis of structure, surface analysis, and fractography.

Book Description
Because thermoplastics have been used in high-performance structural applications only recently, there is a great need for data on their behaviour. This book is dedicated solely to the engineering design analysis of thermoplastic parts. It offers mechanical engineers and materials scientists specific design techniques for predicting stiffness, strength, creep and fatigue of polymeric components. It also includes important information on the use of nonhomogeneous materials such as structural foams and thermoplastic composites.

Book Description
Thermoplastic Aromatic Polymer Composites: A Study of the Structure, Processing and Properties of Carbon Fibre Reinforced Polyetheretherketone and Related Materials deals with the field of thermoplastic composite materials through a study of carbon fiber reinforced polyetheretherketone. The book is composed of twelve chapters. The first four chapters are an introduction and basic learning of thermoplastic composite materials. These chapters include discussions on the components of thermoplastics, product forms, and the microstructure of aromatic polymer composites. The processing and manufacturing technology, including the fundamental operations, control, and the wide implications of manufacturing the composite material, are analyzed. The service performance structure of three interactions, namely, material, design, and processing, are illustrated. The strength of thermoplastic composites is then considered through an analysis of both shear and extensions with elastic modulus, but in the case of material strength, the differences between tension and compression properties should be taken into account. The book also notes that the durability, temperature sensitivity, and environmental resistance should likewise be regarded for a structural composite to have practical value and satisfactory performance. Lastly, the text explains that the numerous applications of thermoplastic structural composites, such as in medicine, aviation, marine and space technology, automotive, and industrial machinery, are all important and a rigorous evaluation is therefore necessary. The book finally suggests that the research into the future developments in the thermoplastic structural composites and the trend toward new design strategies and processing technology are important in optimizing the composite's great potential. Industrial researchers in the field of chemistry and polymer composites, students, and academicians interested in the design and application of polymer composites will find this book relevant.

Book Description
This thesis describes the investigation and development of damage modelling techniques for woven long glass fibre reinforced polypropylene matrix composites. The objective of the work was to develop and validate predictive models for the intralaminar damage behaviour of these materials, with the aim of applying the results to an industrial demonstrator component. Two damage modelling methods were investigated. The first, based on ply-level failure criteria and implemented in an implicit finite element code, was developed and validated using a range of coupon tests for a balanced weave 60% weight fraction commingled glass/polypropylene composite. The second method utilised a model previously implemented in the commercial explicit finite element code, PAMCRASH. This model was calibrated and validated using the same coupon tests as the first model. The models were subsequently used to simulate an industrial demonstrator component, during a two-phase design and development programme. The demonstrator, an automotive side intrusion beam, was designed and predictively modelled using the two damage modelling techniques investigated. Finally, the composite component was compared to a steel side intrusion beam, using a quasi-static vehicle test to a current legislative standard. This test showed comparable performance in terms of strength and stiffness for the two beams. It was concluded that the implicit finite element damage modelling technique can account for the damage and failure modes observed in a woven glass fibre reinforced polypropylene composite, but is limited when considering high levels of material nonlinearity and damage development, due to the stability of the implicit finite element method. It was also concluded that the explicit finite element technique was more suited to the simulation of damage development in thermoplastic matrix composite components, although the research showed that the model investigated was limited when considering shear damaging behaviour in a woven fibre reinforced composite.

Book Description
Textile composites encompass a rather narrow range of materials, based on three-dimensional reinforcements produced using specialist equipment. This book describes the design, manufacture and applications of textile composites. The intention is to describe the broad range of polymer composite materials with textile reinforcements, from woven and non-crimp commodity fabrics to 3-D textiles and their applications. The book gives particular attention to the modelling of textile structures, composites manufacturing methods, and subsequent component performance. This practical book is an invaluable guide for manufacturers of polymer composite components, end-users and designers, structural materials researchers, and textile manufacturers involved in the development of new products with textile composites.
