Today carbon nano tube reinforced composites has a wide application in industry Due to their low weight and high strength.In this thesis, the analysis of carbonnano tube reinforced composite panels in Low-velocity impact will be dealt with.
The problem form is composed ofa CNTRC sheet in above, aCNTRC sheet at the bottom and a Homogeneous layer in the center.The problem in three different boundary conditions and using the Rayleigh-Ritzand Newmark method has been solved.The first chapter is a review of relevant articles over the last few years,The second chapter is aboutnano technology, nanocomposite, Ceramic Nanocomposites, Metal-based nanocomposites, Polymer Nanocomposites,Matrix Material, FillerMaterial, Nanoclaysnanofillers and carbon nanofillers. In the third chapter, deal with the differential equations and equations, and the proof and extraction of the equations and Finally, the fourth chapter discusses the results and charts.The results indicate that there was no significant difference in the graphs with the change in boundary conditionsBut if the four sides of the sheet are clamped, they will have a significant impact on the center displacement of the sheet in terms of time However, by changing the collision geometry, temperature change, velocity change and variation in the volumetric percent of carbon nanotubesOn charts, there will be quite different conditions and trends.
Key words: Nanocomposite, Carbon nanotube, The higher order theory of shear deformation, Center displacement of plate, Contact force, Indention
