Presented by Professor Alan Lau, Hong Kong Polytechnic University, as part of the Platform Technologies Research Institute's Distinguished Lecture series.
Polymer-based advanced composites always suffer from degradation at extreme temperatures in the range between 220 and 77 K and low atmospheric pressure.
This seminar will provide an overview on the nanocomposites and their mechanical, thermal and structural properties at different working environments.
The following key items will also be introduced:
- design of the heat shield’s geometry for re-entry vehicles
- shock wave effect in relation to the heat transmission to the vehicles
- advantage of using Phenolic Resin Carbon Ablator (PICA)
- types of nanoparticles for property enhancement for the vehicles
- possibility of using nano-particles (nanotubes, nanoclay, nano-silica, silica-aerogel, etc) to enhance the effectiveness of pyrolyzing process of PICA to prolong the heat transfer.
The potentiality of using different structural monitoring techniques to serve at the extreme environment will also be discussed.
