Fractography of an Interlaminar Shear Fracture in a Carbon Fibre-Reinforced Epoxy Composite Enhanced with Carbon Nanotubes

Popis výsledku v původním jazyce

Fibre-reinforced polymer composites are successfully used in the aerospace industry. The presented paper focuses on a fractographic interpretation of an interlaminar shear structural fracture in a composite with an epoxy matrix enhanced by carbon nanotubes. A double-notch shear loading test was performed to assess the influence of the multi-walled carbon nanotubes on the essential mechanical property of the laminated composite - interlaminar shear strength. The shear stress state in the specimens duringloading and the test boundary conditions were verified through the finite element method. Failure mechanisms were determined by means of light and scanning electron microscopy. Fractographic features typical for interlaminar shear loading were observed.Resin aggregates were also observed in the nano-enhanced specimens. The aggregates indicate an insufficient distribution of nanotubes in the resin which might cause the non-significant change in the strength obtained in the experiment.
