《纺织复合材料》课程参考文献（High Performance Thermoplastic Resins and Their Composites）Foreword

Foreword This book describes recent developments in high performance thermoplastic resins and their com- posites and assesses the benefits and limitations of these emerging materials for aerospace and other applications.Discussions on the performance of neat and continuous fiber reinforced ther- moplastic resins in terms of their properties and environmental and chemical resistance are pro- vided.The interrelationships between morphology and properties of semicrystalline thermoplastic composites are addressed as well as the factors influencing the morphology.The various techniques to combine fibers and matrix,to produce high quality laminates,to form three-dimensional parts and to join thermoplastic composite parts are described.One section is devoted to presenting some examples of aircraft applications of thermoplastic composites.General conclusions and recommendetions for future research and development work are made. Recently,a range of commercial composites based on thermoplastic matrix resins have been de- veloped for high-temperature structural applications.These new thermoplastic composites are based on aromatic polymers and surmount the major limitations of earlier aliphatic based ther- moplastic polymers such as low elastic modulus,low giass transition temperature and poor solvent resistance.The replacement of metallic and fiber reinforced thermoset components with thermo- plastic based composites is now emerging.Although they are not likely to completely replace thermosets,at least in the near future,they offer potential advantages over thermosets for de- manding applications (that reinforce the competition between these two classes of advanced rein- forced plastics).In general,thermoplastics have an indefinite shelf life,low moisture adsorption, good thermal stability,high toughness and damage tolerance,short and simple processing cycles, and potential for significant reductions in manufacturing costs.In addition,they have the ability to be remelted and reprocessed. The materials considered here include thermoplastic polymers belonging to various chemical classes such as polyketones,polyarylene sulfides,polyamides,polyimides,polysulfones,liquid crystalline polymers,polybenzimidazoles and polyphenylquinoxalines.The main characteristics of these families are discussed. The first part of the book revicws the thermal and mechanical properties of the neat thermo- plastic resins as well as their chemical and moisture resistance and toughness properties.

Foreword This book describes recent developments in high performance thermoplastic resins and their com￾posites and assesses the benefits and limitations of these emerging materials for aerospace and other applications. Discussions on the performance of neat and continuous fiber reinforced ther￾moplastic resins in terms of their properties and environmental and chemical resistance are pro￾vided. The interrelationships between morphology and properties of semicrystalline thermoplastic composites are addressed as well as the factors influencing the morphology. The various techniques to combine fibers and matrix, to produce high quality laminates, to form three-dimensional parts and to join thermoplastic composite parts are described. One section is devoted to presenting some examples of aircraft applications of thermoplastic composites. General conclusions and recommendetions for future research and development work are made. Recently, a range of commercial composites based on thermoplastic matrix resins have been de￾veloped for high-temperature structural applications. These new thermoplastic composites are based on aromatic polymers and surmount the major limitations of earlier aliphatic based ther￾moplastic polymers such as low elastic modulus, low glass transition temperature and poor solvent resistance. The replacement of metallic and fiber reinforced thermoset components with thermo￾plastic based composites is now emerging. Although they are not likely to completely replace thermosets, at least in the near future, they offer potential advantages over thermosets for de￾manding applications (that reinforce the competition between these two classes of advanced rein￾forced plastics). In general, thermoplastics have an indefinite shelf life, low moisture adsorption, good thermal stability, high toughness and damage tolerance, short and simple processing cycles, and potential for significant reductions in manufacturing costs. In addition, they have the ability to be remelted and reprocessed. The materials considered here include thermoplastic polymers belonging to various chemical classes such as polyketones, polyarylene sulfides, polyamides, polyimides, polysulfones, liquid crystalline polymers, polybenzimidazoles and polyphenylquinoxalines. The main characteristics of these families are discussed. The first part of the book reviews the thermal and mechanical properties of the neat thermo￾plastic resins as well as their chemical and moisture resistance and toughness properties. The second part of the book concerns the performance of advanced thermoplastics reinforced with continuous carbon fiber.
