Fiber studies problem solving application

As a new kind of carbon materials, carbon nanofilaments (tubes and fibers) have been studied in different fields [1]. But, until now far less work has been devoted to the catalytic application of carbon nanofilaments [2] and most researches in this field are focused on using them as catalyst supports. When most of the problems related to the synthesis of large amount of these nanostructures are solved or almost solved, a large field of research is expected to open to these materials [3]. In this paper, CNF is tested as a catalyst for oxidative dehydrogenation of propane (ODP), which is an attractive method to improve propene productivity [4]. The role of surface oxygen annplexes in catalyzing ODP is also addressed. 

Extensive research has been undertaken in blending different polymers to obtain new products having some of the desired properties of each component. Among protein- and polysaccharide-based green materials, those made from soy protein (Maruthi et al. 2014 Ghidelli et al. 2014 Behera et al. 2012) and starch (Katerinopoulou et al. 2014 Flores-Hemandez et al. 2014) have been extensively studied for and their physiochemical properties been analyzed. The literature review clearly shows that development of biodegradable biopolymer-based materials based on these materials can not only solve the white pollution problem but also ease the overdependence on petroleum resources. This chapter provides a brief overview of the preparation, properties, and application of cellulose fiber-reinforced soy protein-based and starch-based biocomposites. 

In Section 2.5, the application of adaptive fiber composites to influence the behavior of helicopter rotor blades is outlined. To simulate such a system, an adaptive beam, as considered in the two previous chapters, needs to be examined in the rotating environment. Besides the already complicated interactions due to arbitrary mechanical and electromechanical couplings, this requires consideration of additional couplings due to gyroscopic and second-order theory effects. Consequently, the general problem may only be solved with the aid of discretization, to be accomphshed here by means of the finite element method. Analytic solutions of manageable complexity, however, may be found for simplified problems and can be utilized for fundamental studies and to support the validation of the finite element solution. 

The potential use of natural fiber composites is diseussed in this chapter. One of the most important reasons for the increasing trend in the production of natural fiber eomposites is due to easy and economical disposal of the wastes. There is a lot of scope in the future for researchers and industrialists in the field of natural fiber reinforced composites. A significant amount of research work has been carried out in the field of natural fiber composites and yet more investigations have to be made with polymer composites. To wider the applications of these fibers in solving environmental problems, more studies have to be continued in the future.
