Article Preview

In this research the effects of the nano-particle additions and two different fabric architectures of knitted E-glass fibers on the mechanical properties of polyester fiberglass composites were investigated. The particles selected was 50 nanometer in size Al2O3 particles. E-glass fibers were knitted using two different molds by two different arrangements. Specimens were machined and mechanical tests were conducted as per the accepted test standard. Tension, impact and fracture properties were measured and their associated failure modes were compared with each other. Fracture behavior of specimens with and without nano-particle addition in unidirectional tensile test was studied using Scanning Electron Microscopy (SEM). Results obtained showed that tensile strength of the composite is significantly dependent on nano-particle addition and E-glass fiber architecture. Addition of 0.2 weight percent nano-particles enhances the tensile properties of polyester fiberglass composites. It was found that fracture behavior of composite depends strongly on nano-particle addition.
