Development Of Energy Absorbing Laminated Fiberglass Composites Using Electrospun Glass Nanofibers, Evan Kimbro

Dissertations

The ability to predict failure of composite laminates due to delaminations is critical because of its subsurface nature. Traditional strengthening methods such as stitching and Z-pinning, while improving interlaminar properties in woven composites, lead to a reduction of the in-plane properties. Electrospun non-woven sheets of nanofibrous mat applied at interfacial regions offer an option to traditional treatments. Applications where protrusion energy must be dissipated completely would benefit the most from the use of the electrospinning treatment. Examples are bullet proof vests and vehicle armor. Penetration of a projectile through a composite material may be avoided by creating more energy absorbent …
