International. Incorporating nanomaterials into the polymer matrix is considered to be a highly effective technique for improving the mechanical properties of resins.
Researchers have examined the effects of adding different nanoparticles such as single CNT walls (SWCNT), double CNT wall (DWCNT), multiple CNT walls (MWCNT), graphene, nanoclays and nanosilica on breaking strength, strength and stiffness of the epoxy matrix.
In the study, the Young module (E), tensile strength (UTS), mode I (GIC) and mode II (GIIC) of resistance to breakage of the various nanocomposites to different nanoparticle charges were compared.
The review showed that, depending on the type of nanoparticles, the integration of the nanoparticles has a substantial effect in mode I and mode II of breaking strength, strength and stiffness. Critical factors are highlighted, such as the maintenance of a homogeneous dispersion and the good adhesion between the matrix and the nanoparticles.
The effect of surface functionalization, its relevance and the hardening mechanism was also examined and discussed. A wide variety of data consist of the mechanical properties of hardened nanomaterial compounds reported to date, therefore they have been compiled to facilitate the evolution of this emerging field, and the results are presented on maps showing the effect of nanoparticles carrying mode I breaking resistance, stiffness and strength.
