Available in PDF, EPUB and Kindle. Book excerpt: In this study the potential of utilizing poly(acrylic acid) (PAA) and polyvinylpyrrolidone (PVP) blends as improved thickening agents of aircraft de-/anti-icing fluids is investigated. Current fluid thickeners commonly comprise PAA homo or co polymers and two examples are investigated in terms of their structure, characteristics, size and the rheological profile as aqueous and solutions in a typical glycol based deicing fluid . The rheological properties of these polymer thickeners are found to be sensitive to composition, electrolyte concentration and pH as well as temperature. The rheological and aerodynamic performances of thickened water glycol mixtures were evaluated under the conditions typically experienced by de icing fluids. A model is also develop ed to simulate the rheological behaviour of the polymer solutions. The model involves consideration of reptation, relaxation of the chains by slippage or loop relaxation, and normal Rouse dynamics is appropriately adapted to reflect the structural changes of the polymer molecules and the consequent pseudoplastic behaviour. The model has helped with development of an understanding of the way in which these polymer systems create the rheological characteristics which are necessary for the action of the fluids in protecting the aircraft during the period it is at the stand and also in the initial stages of taxiing and take off. For the purpose of developing improved thickening materials with proper de icing ability and reduced gel formation tendency, various PV P PAA blends are formulated and rheologically examined together with wind tunnel testing. The gels have a tendency to form insoluble deposits which are capable of jamming the ailerons and flaps during flight. The influences of multiple mono and di valent cations, with which de icing fluids are commonly diluted was investigated. The PVP PAA blends achieve the characteristic rheological properties through a different set of interactions from those of pure PAA and are shown to be less sensitive to electrolyte effects. This study has identified a new potential de-icing fluid system.

Download or read book Thermal Spray Coating of Polymeric Composite Materials for De icing and Anti icing Applications written by Alireza Rahimi and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Proper removal of accreted ice from the structures that are usually in contact with the harsh and cold weathers has always been a big challenge for the industry. Different methods and technologies have been adopted for ice management in wind turbines and aircraft. The purpose of this thesis is the fabrication of an electro-thermal heating element, as de-icer or anti-icer, for polymer-based composites. In this study, the plasma spray technique was utilized for the deposition of a nickel-chrome-aluminum-yttrium (NiCrAlY) coating layer as a heating element on top of a glass fiber-reinforced polymer composite (GFRP). For the fabrication of a high-quality and appropriate heating element coating layer, three types of composite samples with different surface types were manufactured. The first composite type was fabricated by the stacking of 16 GFRP prepregs, the second type was fabricated by the stacking of 16 GFRP and a 200 stainless steel mesh cloth as the top layer, and the last composite type was fabricated by the stacking 16 GFRP prepregs and a 400 stainless steel mesh cloth as the top layer. Moreover, to find the NiCrAlY powder with the proper particle size distribution for the generation of a heating element, two types of NiCrAlY powder with the fine and coarse particle size distributions were used for the coating of the composite samples. After coating of the composite samples with different spray parameters, and examining them under an optical microscope, it was found that using a 200 stainless steel mesh as the top layer of the composites makes a significant improvement in the uniformity, adhesion, deposition efficiency, and quality of the coatings. For more analysis, several tests were conducted on the coated samples for determining their mechanical and electrical properties. It was found that using a proper surface modification method and set of spray parameters could result in improving the coating bonding strength significantly. The electrical and thermal analyses of the coated samples also showed that the coated samples have a high capability in the generation of heat and acting as a heating element.

Book excerpt: This unique book presents ways to mitigate the disastrous effects of snow/ice accumulation and discusses the mechanisms of new coatings deicing technologies. The strategies currently used to combat ice accumulation problems involve chemical, mechanical or electrical approaches. These are expensive and labor intensive, and the use of chemicals raises serious environmental concerns. The availability of truly icephobic surfaces or coatings will be a big boon in preventing the devastating effects of ice accumulation. Currently, there is tremendous interest in harnessing nanotechnology in rendering surfaces icephobic or in devising icephobic surface materials and coatings, and all signals indicate that such interest will continue unabated in the future. As the key issue regarding icephobic materials or coatings is their durability, much effort is being spent in developing surface materials or coatings which can be effective over a long period. With the tremendous activity in this arena, there is strong hope that in the not too distant future, durable surface materials or coatings will come to fruition. This book contains 20 chapters by subject matter experts and is divided into three parts— Part 1: Fundamentals of Ice Formation and Characterization; Part 2: Ice Adhesion and Its Measurement; and Part 3: Methods to Mitigate Ice Adhesion.
