Please describe the project specifications.
A Japanese company reached out to us to develop a heat shield barrier system that can be used for controlling nuclear power plants during natural disasters. The client needed to protect existing cable trays from high temperatures and fire, because during the Fukushima Daichi plant disaster, the controlling cable systems for the plant were destroyed by the fires, and thus the plant was unable to control its systems. The interior of the heat shield needed to withstand internal temperatures of 120 degrees C to 180 degrees C while the exterior (i.e. the flame exposed side) had to withstand a constant temperature of 1200 degrees C for a time period of up to 4 hours. We accomplished such and extreme requirement by using a combination of proprietary designed flexible ceramic and other materials that we had previously used in our aerospace applications. The assemblies were tested per ISO834 and passed all requirements including bringing down the temperature from 1200 degrees C on the flame exposed side of the assembly to 120 degrees C and 180 degrees C range on the inside of the assembly for a period that exceeded the 4 hour criterion.

What was the purpose of this project? What did the client request?

What is unique or complex about the project?
In order to protect cable trays from extreme high temperature and flame, we needed to opt for ceramic made material. Since we needed to strengthen the barrier, we layered combination of materials and quilted them with ceramic thread to hold them together. Sewing with ceramic thread required advanced sewing skills due to the delicacy of the thread. The thickness of the layered fabric was also a challenge.

What were the results of the project?
We have created a third party proved product prototype that can be extremely valuable and applicable for many emergency situations in order to protect from hazardous elements often caused by natural disasters.
