Nano-Aramid Fiber Reinforced Polyurethane Foam [PDF]

open access: yes, 2008
Closed cell polyurethane and, particularly, polyisocyanurate foams are a large family of flexible and rigid products the result of a reactive two part process wherein a urethane based polyol is combined with a foaming or "blowing" agent to create a ...

Zinc Oxide Nanowire Interphase for Enhanced Lightweight Polymer Fiber Composites [PDF]

open access: yes
The objective of this work was to increase the interfacial strength between aramid fiber and epoxy matrix. This was achieved by functionalizing the aramid fiber followed by growth of a layer of ZnO nanowires on the fiber surface such that when embedded ...
