Secondly, the oxides in the coating improve the fracture toughness.
These results are here applied to the three different types of Polish flint from the Holy Cross Mountains, in order to relate the different uses to which these flints were put to their fracture toughness and petrology.
Engineers found other alloys with greater corrosion resistance but they lacked the required structural strength and fracture toughness.
The significantly higher fracture toughness of the DGEBF/D-MWCNT composite compared to that of the DGEBF/P-MWCNT and DGEBF/A-MWCNT composites is attributed to its higher dispersion homogeneity in the epoxy matrix; this higher fracture toughness resulted possibly from the increased adhesion between the D-MWCNT and the epoxy matrix, induced by the curing reaction between the DMWCNT surfaces and the epoxide group [19, 33-35],
The JIP will involve detailed experiments and analysis to provide a better understanding of the key parameters known to impact fracture toughness test results.
Mechanism of improving fracture toughness in the presence of carbon nanotubes can be defined as bridging of nanotubes on the opening of fracture and preventing the growth of fracture, taking out the nanotube from the background (a parameter in fracture energy consumption) and fracture deviation (increasing the path of fracture and consequently increasing the toughness).
