Purpose: Scanning electron microscopy and light microscopy with polarization has been used for observation cross sectioned samples of nanocomposites with developed layered region, visible in the polarized light; Purpose of this work was to focus on investigation of nanocomposites, with polyolefin matrix and nanometric 2:1 silicate reinforcement, as future engineering materials, Design/methodology/approach: Process of injection molding has been used to manufacture nanocomposites; conventional mold equipped with special hydraulic pressure system and connected to external computer for controlling flow movements inside mold cavity Findings: Layered region, with medium thickness of layer equal to 200 microns, obtained due to the melt manipulation of polymer, improved fracture toughness of investigated nanocomposites; nanoparticles located in the matrix make llalom-like crack propagation extending fracture due to bypassing parallely oriented nanoclay tactoids Research limitations/implications: Specimen shape used in the experiment is rectangular and obtained data of investigated specimens approve very good reinforcement along specimen, application of mre complicated shapes may perturb uniform distribution of nanoparticles in the matric and affect mechanical properties Practical implications: Application developed injection moulding technique and nanomaterials gives possibility to obtain layered region with raised toughness and simultaneously obtain cheaply nanocomposites, thanks to economical technology of manufacturing and commercially available polyolefins at low price Originality/value: Accordingly to increment of plastic market and its upward tendency, wide range of products and applications (and still increasing) in different sectors including medical, household appliances, furniture, automotive, aerospace, electronics and buildings.
