Binary Nanoparticles Filled Fiber Reinforced Composites for Enhanced Damage Tolerance and Fatigue Life Subjected to Marine Environments
Abstract
Objective of the proposed activities will be to develop novel hybrid bulk nanostructured composite materials for naval applications that will be stronger, lighter and more durable that the current generation materials. We will develop novel hybrid nano structured materials using binary (combination of nanoclay/multi-walled carbon nanotubes and nanoclay/graphene nanoplatelets) nanoparticles and determine their thermal, viscoelastic, tensile, flexural, static and high strain rate compression, tensile-tensile fatigue, low and high velocity impact properties. Thermoset polymeric epoxy matrix will be modified with binary nanoparticles utilizing combinations of sonication, magnetic stirring and three-roll calendaring processes which have been optimized through ongoing research at Tuskegee University. Mechanical, thermal and viscoelastic properties of the modified polymers will be determined and the most optimal nanoparticle loadings will be utilized for fabricating laminated composites. Rheological studies will be carried out to determine the viscosity variation, information of which will help during fabrication of laminated composites. For the fabrication of laminated composites with matrix modified with nanoparticles, we will use carbon and glass fibers individually and hybrid of both utilizing combinations of hand layup and compression mold processes. Fabricated composite specimens will be subjected to saline water, cold (subzero: dry, wet) and room temperature conditioning for different time (30, 60, 120 and 240 days), upon completion of which various properties outlined earlier will be determined. It is anticipated that new materials that are stronger, durable, more damage tolerant will be developed.
