Re: [PSUBS-MAILIST] Glass microspheres idea
Sorry for not being clear; yes I am thinking of building floats. The idea is to have an easy syntactic foam replacement that takes advantage of the higher psi glass bubbles and offsets their higher density by just filling a fiberglass container with them instead of adding them to a epoxy resin as normally done from creating syntactic foam.
To build the container, you could cut styrene foam to fit your hull shape and desired external shape, then cover the styrene foam with a durable layer of fiberglass. You might want to embed aluminum sheeting for armor, especially on the external side but also for mounting tabs that will make it easy to bolt the float onto the hull. Then drill a hole through the fiberglass; dissolve the styrene foam with acetone; refill the container with glass bubbles; and seal the hole.

Doug,
(most of) The space will
be consumed. Is your idea only for buoancy reason??
Regards, Emile
I was wondering about using glass microspheres and air as a filler in a
fiberglass compartment. For example, build a figerglass tank, then fill
it with 10,000 psi glass bubbles and seal it off. I know each sphere
would be loaded at points of contact with it neighbors but I seems like it
would work to at least 3000
ft.
Please let me know what you think.
