Hybrid Fire Extinguisher Cylinder

Last week, i met with the inventor of the maintenance free fire extinguisher, at a fire and safety exhibition in Singapore.  So, i got a closer look at the product and got first hand information from the inventor himself.  There are few things i learned:

a) the cylinder consist of 3 layers, a plastic bottle in the inside, a layer of reinforcement yarn in the middle and another plastic bottle on the outside

b) the reinforcement yarn is not rigidly binded, like the CNG Composite cylinder.
It is tightly wound around the inner plastic container.

c) the reinforcement yarn used is Kevlar from Dupont, not ordinary Glass Fibre, talking about Kevlar, maybe you should know this news.

d) 2 pressure gauges are fitted, i suppose to reduce the failure probability

e) the Valve is solid brass, Malaysia Made, i was told, so you see, Malaysia Boleh!

f) the cylinder passed crushing test.  In this test the cylinder is pressed until both walls almost touching, then inflated back to original size, and it shall nor leak

Here is a photo of the inventor (middle) with another 2 of my Singaporean friends.

I suggested to the inventor to name the cylinder as a hybrid fire extinguisher container, as it combines more than one method of fabrication.
