Awesome info!  Thank you, Craig.  I had found a study commissioned by the 
DOT/FAA on flammability of aircraft panels that indicated the raw fibers were 
essentially non-combustible, but I was hesitant to classify it as such.  Much 
appreciated!

Subject: RE: Carbon Fiber Protection

The raw fiber isn’t a class III, it won’t burn, actually burning it, the 
Carbonization process, “burns” the material.  The spools on which the fiber is 
wound are actually more of a hazard (and not really much of one) than the fiber 
itself.

The finished product shouldn’t be sensitive to water so the only real reason 
for a preaction would be due to an owner having problems with a “leaking” 
sprinkler system ruining packaging.

We have had one CF project where the finished product was required to be housed 
for a period of days in a controlled environment before its finally testing and 
QC certification prior to shipment.  If product had gotten wet due to a faulty 
sprinkler system, the test results for the exposed product may no longer be in 
spec.

But on other CF projects there has never been any concern by the owner 
regarding the type of sprinkler system in any part of the process from start to 
storage.

Mike – Good thought!  I’ll make sure to keep that in mind.

Todd – Thank you for the input.  Those are great questions and we will keep 
them in mind as we continue discussions with the owner.

I would need to know more details about the occupancy. Are they dealing with 
fibers, pre preg or finished products? Are they dealing with products that are 
oven cured and need to cool down? Is there a product that is susceptible to 
water damage?

I have contractor client who has been asked to provide a quote for a preaction 
system to protect a business whose primary storage commodity is carbon fiber.  
The contractor is meeting with them today to try to understand why they are 
requesting preaction.  I have searched information from both NFPA and FM Global 
and have found no specific direction.  If the storage is for the fiber itself 
(raw material) I am thinking it falls under a class III commodity.  If it is a 
finished product (auto/aircraft body panels, etc.) I am thinking the commodity 
will depend on the type of resin used in the construction.  Either way, I don’t 
see a reason for a preaction system.  My client and I feel the owner has had a 
problem with an unreliable sprinkler system in the past and is trying to avoid 
the problems that come with that by requesting the preaction system.  Just 
wanted to get the opinions of the group before we give the owner a 
recommendation.

Thank you,
