Advanced Materials for Applied Science and Technology II
Selected, Peer Reviewed Papers From the 9th International Bhurban Conference on Applied Sciences and Technology, January 9-12, 2012, Islamabad, PakistaneBook - 2012
The design and market forces driving the never-ending quest for improved materials for aerospace vehicles include lower weight, improved corrosion and fatigue resistances and lower acquisition and operating costs. The application of composite materials to commercial aircraft, and their extrapolation to next-generation aircraft, has led to significant overall weight-savings; which translate into enhanced range, payload and endurance. The most significant current barriers to an increased use of composite materials are high manufacturing costs, poor reliability in estimating design and development costs, and the inability to predict accurately structural failure. As advanced composites having superior physical and mechanical properties are being eagerly sought, optimization of their processing, design parameters, failure modes and multifunctionality are also being sought. Hence activities in advanced materials focus on the Design and Analysis of Composite Materials, Processing of Polymer Composite Materials, Failure Mechanics of Composite Materials, Shape Memory Polymer Nanostructured Materials and Specialty Coating, Alloys and Metals. The focus is more on tailoring materials with specific properties than on the use engineers will put them to. The 12 papers include discussions of such matters as characterizing hyperelastic (rubber) material using uniaxial and biaxial tension tests, the thermo-mechanical testing of epoxy shape memory polymer composites, a microscope study of a propellant binder, the design of tape-wound composite cylindrical shells incorporating different failure criteria and winding kinematics, the sintering and morphology of porous structure in nickel titanium shape memory alloys for biomedical applications, and hydroentangled polymer-glass bi-layer fibrous composites.
