چکیده
|
The effects of surface-functionalized na^+-montmorillonite nanoclay particles on the flexural behavior of e-glass fiber-reinforced aluminum (glare) laminates were investigated. the nanoclay particles were subjected to surface functionalization using 3-(trimethoxysilyl)propylamine to increase their compatibility with the epoxy matrix and improve their dispersion within the matrix. experimental results indicated that the glare laminates achieved the highest flexural strength (61%) and energy absorption (51%) at an addition of 3 wt% functionalized nanoclay. the highest flexural modulus (67% increase) was observed at an addition of 5 wt% functionalized nanoclay. the flexural properties of the functionalized nanoclay-filled glare laminates were significantly better than those of untreated nanoclay-filled glare laminates. microscopic observations suggested that the introduction of functionalized nanoclay particles markedly enhanced the interfacial adhesion between the matrix and the e-glass fibers.
