Role of using some Hybrid Nano-Fillers on the Strength and Creep Resistance of Fiberglass/Epoxy Composit

Abstract

The effect of adding hybrid nanomaterials (multi-walled carbon nanotubes (MWCNT) with calcium carbonate (CaCO3)) was studied and compared with the effect of adding only one of those nanomaterials and without any addition on creep behavior at 40 ° C and constant applied load. Two different additives weight ratios were studied (1% and 2%) from the weight of epoxy. Three layers of Bi-directional (0-90) glass fibers used as reinforce material the epoxy matrix. vacuum bag technology and sound wave device were used for samples preparation according to the standards. The Samples were tested with crawl tester designed and manufactured according to engineering specifications and standards. The results showed that there was an improvement in the creep behavior and a high creep resistance of the samples with the hybrid nanocomposites compared to the neat samples.
