Abstract

Lap joints of glass/epoxy (GFRP) laminates were made with an adhesive modified with nanofillers and studied in comparison with the control one. An ambient temperature curing epoxy used for making structural composites was also modified with nanofillers and its bond strength (lap shear) characteristics were evaluated in comparison to the virgin resin. Amine functionalized carbon nanofibers and silane modified nanosilica were used at concentrations of 0.1, 0.3 and 0.5% for altering the adhesive properties. Well dispersed nanofillers in the adhesive are found to have no significant effect on the lap shear strength of the GFRP composites.
