It varies enormously. See the link below to a table showing all sorts of glass and glass-like products:
2.6g/cm3
2600Kg/m3
Also glass sinks because it has a density higher than 1.0g/cm^3.

Fibre reinforced plastic is often used in construction, automotive, marine and aerospace. It's made of a polymer matrix reinforced with fibres. Some examples of those fibres are glass, aramid, carbon and basalt.

Glass-reinforced plastic (GRP) is a composite material or fiber-reinforced plastic made of a plastic reinforced by fine fibers made of glass. Like carbon fiber reinforced plastic, the composite material is commonly referred to by the name of its reinforcing fibers (fiberglass)Read more: What_is_the_difference_between_GRE_pipes_and_GRP_pipes

A sailing dinghy is made of glass-fiber reinforced plastic (GRP). Basically, plastic.

PRG (plastic-reinforced glass) and a brass or steel outline.
No its not, its very stiff, poly urathane is more flexable and a hell of a lot more durable. Thin thin layers of fiber glass, like 1 or 2 sheets is flexible and not durable, breaks very easily. But reinforced plastic fiberglass, flexible, no its not, very very stiff.
there isn't one apart from if it shatered
Fiberglass is commonly used for making glass-reinforced plastic (GRP) due to its strength, durability, and versatility. Fiberglass is composed of fine glass fibers embedded in a polymer resin matrix, which when combined forms a strong and lightweight material suitable for a variety of applications.

•Spray-up is an composites fabrication process where resin and reinforcements are sprayed onto a mold. The resin and glass may be applied separately or simultaneously "chopped" in a combined stream from a chopper gun.The glass resin mixed is then rolled by hand to remove air to consolidate the fibers and to get a smooth surface.
Fibreglass (or fibreglass) (also called glass-reinforced plastic, GRP, glass-fiber reinforced plastic, or GFRP), is a fiber reinforced polymer made of a plastic matrix reinforced by fine fibers of glass. It is also known as GFK .
