Re: [PSUBS-MAILIST] floatation



Hi Jay.
 
I have heard mention of syntactic foam here before. How does it keep from compressing the air trapped in the foam
 
from water pressure at depth? I gues the glass spheres wouldn't compress, but how does the foam not squash from the
 
water pressure?
 
Thanks, Bill.

Rick,

Typically syntactic foam is used for buoyancy in deep diving vessels.  It is a solid foam matrix laced with small glass spheres.

i am trying  out a new asme design program and seem to have run into a problem for "death trap one" a thousand foot design. the dam hull weighs too much i have no reserve bouyancy any ideas of good floatsthat would work .its not alvin and i dont think that the epa would let me get by using gasoline
