Composite materials are of interest to these industries due to their attractive properties including high strength to weight ratio and high modulus to weight ratio. Comprehensive research has been conducted on conventional composite materials to optimize their processing parameters as well as optimize their mechanical behavior and reliability. Although composites provide excellent mechanical properties, certain applications demand improved mechanical behavior as well as the presence of additional properties. Recent developments in polymers have developed nanocomposites, which are composites reinforced by nanoparticles. In these materials, the nanoparticles have shown great enhancements in mechanical properties, thermal properties, and electrical properties. Nevertheless, these composites lack the strength for applications where FRP’s are currently used. The addition of nanoparticles as reinforcement to conventional composites shows great promise to not only enhance the existing properties of these composites, but also add many other properties that would maximize their applications. The promise of substantial multifunctional improvements to the behavior of conventional composites does not come without a cost. The effective reinforcement of the desired properties is a direct function of nanoparticle selection and proper dispersion of such nanoparticles. The objective of this research proposal is to develop long fiber reinforced polymer nanocomposites that combine conventional composites with the added benefits of nanocomposites. One of the main challenges involved in the successful enhancement of properties through the addition of nanoparticles is to overcome the problem of poor dispersion in the polymer matrix. Therefore novel state-of-the-art methods of incorporating and dispersing nanoparticles must be developed.Current methods to produce nanoparticle reinforced composites are very limited. One method involves the direct dispersion of nanoparticles in the polymer matrix, then molding the composite through the related process. This approach dramatically increases the polymer’s viscosity, making the polymer extremely difficult if not impossible to process. The entire approach of this research, involving the incorporation of nanoparticles into the fiber perform is unique. This method involves the sonication of the nanoparticles in a solvent solution under specific sonication frequency and amplitude as well as specific exposure time to optimize dispersion. The solution is then sprayed onto a layer of fiber perform which is on a specialized fluid flow processor to incorporate such nanoparticles through multiple layers of fiber mats. The approach undertaken has shown important improvements in specific properties of the composites, but not to the theoretical potential of improvement. Further development of processing parameters as well as the mechanics of the method itself need to be improved substantially. The mechanical property improvement was studied to determine the enhancement to tensile strength, flexural strength, interlaminar shear strength, impact strength, fatigue life, and behavior under stress concentration caused by geometric discontinuity. A series of testing samples for each specific property testing were produced and tested according to the corresponding ASTM standards. 2009 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1259091518 http://rave.ohiolink.edu/etdc/view?acc_num=osu1259091518 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
