Dependence of the Pukánszky's interaction parameter B on the interface shear strength (IFSS) of nanofiller- and short fiber-reinforced polymer composites

摘要: Abstract In this paper Pukanszky’s model for the tensile strength, originally developed composites filled with quasi-spherical fillers, has been analyzed in terms of Kelly–Tyson prediction mechanical strength reinforced short fibers, often used also nanocomposites organically modified nanoclays and carbon nanotubes. way it was possible to establish a direct link between interaction parameter B fundamental material parameters such as strengths matrix aspect ratio orientation factor interfacial shear IFSS. Also determine minimum value which is predict composite from rule mixtures, well maximum that can achieve case continuous aligned fibers same type matrix, interface strength. Moreover, critical volume fraction, φ crit , defined corresponding amount filler content necessary be greater than unreinforced i.e. σ c  =  m . It shown condition  ≅ 3. A few examples calculations IFSS, τ have provided, using published literature values relating nanotubes, natural fibers.
