Book excerpt: Poly(ether-ketone-ketone) (PEKK) high performance thermoplastics are currently studied with a great interest by the aeronautic industry as matrix for carbon fiber reinforced structural parts. In fact, PEKK composites can be consolidated out of autoclave and they have lower processing temperatures than PEEK composites.The aim of the study was to investigate and predict the evolution of PEKK composite mechanical properties depending on the processing thermal cycle to determine the best processing parameters for PEKK composite part manufacturing regarding processing times and final mechanical performances.A first part investigates the crystallization kinetics modelling of PEKK matrices and the influence of crystallinity and crystalline morphologies on PEKK matrix mechanical properties. A second part focuses on the macromolecular modifications of PEKK matrices at high processing temperatures under air and nitrogen and their impact on PEKK matrices crystallization and mechanical properties. A last part presents the influence of carbon fibers on crystalline morphologies and crystallization kinetics, the manufacturing of unidirectional and ± 45° PEKK composites under press and autoclave and finally the impact of crystallinity and crystalline morphologies on PEKK composite mechanical properties.

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.

Book Synopsis Creep, Fatigue, and Their Interaction at Elevated Temperatures in Thermoplastic Composites by : Mohammadreza Eftekhari
Download or read book Creep, Fatigue, and Their Interaction at Elevated Temperatures in Thermoplastic Composites written by Mohammadreza Eftekhari and published by . This book was released on 2016 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermoplastic composites are suitable alternatives to metals in some load-bearing applications such as in the automotive industry due to a large number of advantages they present. These include light weight, ease of processing for complex geometries at high production rate, outstanding cost to performance ratio, ability to reprocess, and corrosion resistance. Addition of fillers such as talc or reinforcements such as short glass fibers can improve the mechanical performance of unreinforced thermoplastics to a high degree. Components made of thermoplastic composites are typically subjected to complex loadings in applications including static, cyclic, thermal, and their combinations. These applications may also involve environmental conditions such as elevated temperature and moisture which can dramatically affect their mechanical properties. This study investigated tensile, creep, fatigue, creep-fatigue interaction, and thermo-mechanical fatigue (TMF) behaviors of five thermoplastic composites including short glass fiber reinforced and talc-filled polypropylene, short glass fiber reinforced polyamide-6.6, and short glass fiber reinforced polyphenylene ether and polystyrene under a variety of conditions. The main objectives were to evaluate aforementioned mechanical behaviors of these materials at elevated temperatures and to develop predictive models to reduce their development cost and time. Tensile behavior was investigated including effects of temperature, moisture, and hygrothermal aging. Kinetics of water absorption and desorption were investigated for polyamide-6.6 composite and Fickian behavior was observed. The reductions in tensile strength and elastic modulus due to water absorption were represented by mathematical relations as a function of moisture content. In addition to moisture content, aging time was also found to influence the tensile behavior. A parameter was introduced for correlations of normalized stiffness and strength with different aging times and temperatures. Higher strength and stiffness were obtained for re-dried specimens after aging which was explained by an increase in crystallinity. Mechanisms of failure were identified based on fracture surface microscopic analysis for different conditions. Creep behavior was investigated and modeled at room and elevated temperatures. Creep strength decreased and both creep strain and creep rate increased with increasing temperature. The Larson-Miller parameter was able to correlate the creep rupture data of all materials. The Monkman-Grant relation and its modification were successfully used to correlate minimum creep rate, time to rupture, and strain at rupture data. The Findley power law and time-stress superposition principle (TSS) were used to represent non-linear viscoelastic creep curves. Long-term creep behavior was also satisfactory predicted based on short-term test data using the TSS principle. Effect of cycling frequency on fatigue behavior was investigated by conducting load-controlled fatigue tests at several stress ratios and at several temperatures. A beneficial or strengthening effect of increasing frequency was observed for some of the studied materials, before self-heating became dominant at higher frequencies. A reduction in loss tangent (viscoelastic damping factor), width of hysteresis loop, and displacement amplitude, measured in load-controlled fatigue tests, was observed by increasing frequency for frequency sensitive materials. Reduction in loss tangent was also observed for frequency sensitive materials in dynamic mechanical analysis tests. It was concluded that the fatigue behavior is also time-dependent for frequency sensitive materials. A Larson-Miller type parameter was used to correlate experimental fatigue data and relate stress amplitude, frequency, cycles to failure, and temperature together. Effects of temperature and mean stress on fatigue behavior were also investigated by conducting load-controlled fatigue tests under positive stress ratios and at room and elevated temperatures. Larson-Miller parameter was used and a shift factor of Arrhenius type was developed to correlate fatigue data at various temperatures. Effect of mean stress on fatigue life was significant for some of the studied materials, however, for the polyphenylene ether and polystyrene blend no effect of mean stress was observed. Modified Goodman and Walker mean stress equations were evaluated for their ability to correlate mean stress data. A general fatigue life prediction model was also used to account for the effects of mean stress, temperature, anisotropy, and frequency. Creep-fatigue tests were conducted using trapezoidal load signal with hold-time periods. Effects of temperature, frequency, load level, mean stress, and hold-stress position on creep-fatigue interaction behavior were studied. In-phase TMF tests were conducted on polyamide-based composite for the temperature variation between 85 to 120 °C. Significant non-linearity was observed for the interaction of creep and fatigue damage. The applicability of Chaboche non-linear creep-fatigue interaction model to predict creep-fatigue and TMF lives for thermoplastic composites was investigated. A frequency term was added to the model to consider the beneficial effect of increased frequency observed for some the studied materials. The Chaboche model constants were obtained by using pure fatigue, pure creep, and one creep-fatigue interaction experimental data. More than 90% of life predictions by the Chaboche model were within a factor of 2 of the experimental life for both creep-fatigue and TMF test conditions.
