Available in PDF, EPUB and Kindle. Book excerpt: Fusion bonding is one of the three methods available for joining composite and dissimilar materials. While the other two, mechanical fastening and adhesion bonding, have been the subject of wide coverage both in textbooks and monographs, fusion bonding is covered here substantially for the first time. Fusion bonding offers a number of advantages over traditional joining techniques and it is anticipated that its use will increase dramatically in the future because of the rise in the use of thermoplastic matrix composites and the growing necessity for recyclability of engineering assemblies. Fusion Bonding of Polymer Composites provides an in-depth understanding of the physical mechanisms involved in the fusion bonding process, covering such topics as: - heat transfer in fusion bonding; - modelling thermal degradation; - consolidation mechanisms; - crystallisation kinetics; - processing-microstructure-property relationship; - full-scale fusion bonding; - fusion bonding of thermosetting composite/thermoplastic composite and metal/thermoplastic joints. The book focuses on one practical case study using the resistance welding process. This example exposes the reader to the development of processing windows for a novel manufacturing process including the use of experimental test programmes and modelling strategies.

It contains research articles addressing materials, processing, modeling, monitoring, or performance issues with experimental or numerical approaches. Whatever the process, e.g., resistance, induction, ultrasonic, laser or conduction welding, or 3D printing using fused deposition modeling, one of the challenges is to master the interfacial phenomena, structure, and quality in the assembly area (welds), which is rather tricky due to the presence of the reinforcement fibers. Additionally, it is of paramount importance to develop reliable predictive process simulation software and monitor and control the process parameters in situ.

Download or read book Manufacturing of Polymer Composites written by B. Tomas Astrom and published by Routledge. This book was released on 2018-04-27 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential application areas for polymer composites are vast. While techniques and methodologies for composites design are relatively well established, the knowledge and understanding of post-design issues lag far behind. This leads to designs and eventually composites with disappointing properties and unnecessarily high cost, thus impeding a wider industrial acceptance of polymer composites. Manufacturing of Polymer Composites completely covers pre- and post-design issues. While the book enables students to become fully comfortable with composites as a possible materials choice, it also provides sufficient knowledge about manufacturing-related issues to permit them to avoid common pitfalls and unmanufacturable designs. The book is a fully comprehensive text covering all commercially significant materials and manufacturing techniques while at the same time discussing areas of research and development that are nearing commercial reality.

Available in PDF, EPUB and Kindle. Book excerpt: Thermoplastic composites are of increasing interest to the aerospace industry. The melt-processability of the thermoplastic matrix allows for fast manufacturing and assembling techniques, such as thermoforming and fusion bonding, which are also highly suitable for process automation. Fusion bonding involves heating of the interface between the parts to be bonded, application of pressure and finally cooling of the bonded parts. Even though successful commercial application of fusion bonding can already be found in the aerospace industry, a wider use requires additional developments in order to improve the predictability, reliability and robustness of fusion bonded joints. This first of all requires a better understanding of that what is perceived as ‘the load bearing capacity’, as measured by mechanical testing of fusion bonded joints.Two mechanisms that are essential for the generation of the load bearing capacity of fusion bonded joints are (i) intimate contact development, followed by (ii) the interdiffusion of polymer chains across the interface. Although these two mechanisms are a prerequisite for the development of a bond, they are not the only mechanisms that determine the performance of a fusion bonded joint. The physical state of the bond line and the structural morphology of the interface also plays an important role. The objective of this work is to identify, to analyse and, when possible, to quantify the relation between the physical state and the structural morphology induced by the fusion bonding process, and the resulting mechanical performance of the joints. For this purpose, the most relevant variations in physical state and structural morphology, as induced by the fusion bonding process, were identified. These factors were then isolated experimentally, and their effects on the interlaminar fracture toughness of the joints were studied.

Download or read book Single Polymer Composites Made of Slowly Crystallizing Polymer written by Ruihua Li and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Composites are widely used in an increasing number of applications in diverse fields. However, most traditional composite materials are difficult to recycle. Because of their enhanced recyclability, thermoplastic single-polymer composites (SPCs), i.e., composites with fiber and matrix made from the same thermoplastic polymer, have attracted much attention in the recent years. High-performance polymer fibers in combination with same polymer matrices would lead to a fully recyclable single polymer composite that has major ecological advantages. However, because a single polymer is involved in the composite, thermoplastic SPCs manufacturing presents a unique set of technical problems, and different approaches from those in standard composites manufacturing are frequently needed. Two specific issues in SPCs manufacturing are how to produce distinct forms of the same polymer and how to consolidate them. So far, most investigations have been reported on a single-component hot compaction method and two-component molecular methods. However, in these methods, either the processing window is too narrow or some impure materials are introduced into the system. The key issue in thermoplastic SPCs processing is how to melt-process the matrix without significantly annealing or even melting the fiber. To overcome the above drawbacks in existing SPCs processing, particularly to widen the SPCs processing temperature window and to purify the SPCs, a novel SPCs manufacturing process utilizing the characteristics of slowly crystallizing polymers was developed and investigated. Highly oriented and highly crystalline fibers made of a slowly crystallizing polymer are mixed with the amorphous form of the same polymer and then consolidated together under heat and pressure. In this dissertation research, two slowly crystallizing polymers, poly(ethylene terephthalate) (PET) and poly(lactic acid) (PLA), were used as model systems for SPCs processing. To study the deformation and failure mechanisms of PET and PLA SPCs, the SPCs were characterized using tensile test, tearing test, impact test, SEM, optical microscopy, and other methods. The change of crystallinity and orientation of the material forms during SPCs processing were characterized by DSC and XRD. The effects of major process conditions on the performance of the SPCs were studied. It was found that the processing temperature played a profound role in affecting the fiber-matrix bonding property. The compression molded SPCs exhibited enhanced mechanical properties. For the PET SPCs with 45% by weight fiber content the tensile strength is four folds of that of non-reinforced PET. After reinforcement, the tearing strength of the PLA SPCs is almost an order higher than that of the non-reinforced PLA. The fusion bonding behavior of two crystallizable amorphous PET sheets was also studied. Several characterization methods including SEM, TEM and polarized microscopy (either on etched or on non-etched samples) were used to observe interfacial bonding morphology of the crystallizable amorphous PET sheets. For a bonded sample, a layer of transcrystals with a thickness of 1-2 ©+m was found right at the interface. A secondary but much larger zone with a distinct morphology was observed outside the transcrystal layer. With increase of the heating time, the width of the whole interfacial region decreases. The interfacial morphology was found to significantly affect the interfacial bonding quality. The testing results further indicated that high bonding temperature with an appropriate holding time promotes interfacial bonding of two crystallizable amorphous PET.

Download or read book Thermoplastic Aromatic Polymer Composites written by Frederic Neil Cogswell and published by Elsevier. This book was released on 2013-10-22 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
