carbon fiber reinforced plastic

Hello,

I am not familiar with the materials at all. But I came across an
application in which I have to put an elecronic device into a RAT for
biology experiments. I need to seal this electronic device woth some
material which can protect it from water. I read the news on BBC that
swedish navy used carbon fiber reinforced plastic for their new
submarines. I was wonerding that Can I use that material to encapsulate
the device. I do not know about the biocaompatibilty aspects of carbon
fiber reinforced plastic too. Can somebody advice me
1. can I use this material.
2. are there any more options

Thanks
Regards
John
