A Critical Review on Nanoparticle Filled Adhesives for Structural Applications

Abstract

The objective of this review paper is to highlight some of the noteworthy research that has been done on the use of nanoparticles (NPs) to improve the performance of adhesively bonded joints (ABJs) against delamination initiation and propagation. Various nanoparticle applications, such as carbon-based, ceramic-based, and mineral-based nanoparticles, are covered. Interlaminar shear strength, fracture toughness, and fracture energy are the major parameters that have been considered for enhancing FRP delamination and fatigue resistance.The reported results indicatethat the inclusion of NPs in polymeric matrices leads to improvement of various material properties,even though some discrepancies in the results have been noted. Notwithstanding, additional researchis required to address some of the issues that have not yet been tackled.
