Abstract

Delamination is a major mode of failure in laminated composites. This paper addresses development of advanced delamination resistant composites using interlaminar SiO 2 nanofibers. The SiO 2 nanofibers were manufactured using Tetra Ethyl Orthosilicate (TEOS) sol gel. The sol gel viscosity of 100-200 cps Voltage of 18kV and distance between spinneret and grounded collector plate of 80 mm were found to be suitable for maximizing production of electrospun fibers. It was observed that typical electrospun fibers were of 300 nm diameter after they were sintered at 600 degrees C. These SiO 2 nanofibers produced using electrospinning were then integrated into fiber glass Epon 862 resin matrix composites. During mechanical characterization of these three phase (fiber glass+Epon 862+SiO 2 nanofibers) composites, extensive experimentation was carried out as per the ASTM D 5528 standard to study the influence of electrospun SiO 2 nanofibers on the Mode I fracture toughness of fiber glass composites. Other characterization studies were related to determining the effect of SiO 2 nanofibers on short beam shear strength, flexure properties, and tensile properties of three phase composites.
