ABSTRACT
This chapter describes an approach to predict the effect of material and manufacturing uncertainty on nanocomposite fatigue life. A multiscale micromechanics technique has been proposed to characterize the nanocomposite material constituting of matrix reinforced/infused with silica spherical shaped nano-size particles. The chapter explains the in situ silica nanoparticles and the diglycidyl ether of bisphenol A matrix strength and stiffness material properties. The multiscale composite refers to conventional fibers, which are used with an enhanced matrix to improve the properties of the epoxy matrix by incorporating second phase fillers into the resin. C. M. Manjunatha et al. presented their experimental process to create nanocomposite and multiscale composite material system that consisted of silica nanoparticle infused epoxy and E-glass fibers reinforcing silica nanoparticle infused epoxy, respectively. At the end probabilistic analysis was utilized to determine the sensitivity effect of nanomanufacturing and matrix and nanoparticle material properties parameters on the fatigue life.
