olymer nanocomposites are materials that have great potential in a variety of applications. By incorporating nanoscale
particles of a filler material, the performance and properties of the bulk material can be drastically altered. Indeed, quite
exceptional improvements can be achieved with small amounts of filler. To make nanocomposites economically viable, i.e. use
them in massive applications, their production must use common processing equipment, and additional processing steps should
be avoided. Many thermoplastic-composites are processed by an injection moulding process. It is generally accepted that the
performance of polymer nanocomposites is intimately related to the degree of dispersion of the nanofiller: good dispersion
and exfoliation may lead to the expected improvement in properties. This dispersion depends on factors such as the affinity
and compatibility of the filler with the matrix, the matrix viscosity and the applied thermo-mechanical level, which depends on
the processing conditions. The understanding of the fracture, microdeformation and mechanics of failure of nanocomposites
is crucial for engineers. In this work the relationship between processing and performance is reviewed for different injected
thermoplastic pieces. The combined effects of the moulding technique and the nano filler on the properties of the polymer
composites are reported. Also, the effect of the occurrence of in-homogeneities, such as weld lines or flow lines in microstructure
and therefore in performance are summarized.
