Abstract
Ballistic resistant articles having excellent resistance to deterioration due to liquid exposure. More particularly, ballistic resistant fibrous composites and articles that retain their superior ballistic resistance performance after exposure to liquids such as sea water and organic solvents, such as gasoline and other petroleum-based products.
Claims27
A fibrous composite material, comprising in order:
- a) a first outer polymer film;
- b) a first fibrous layer in contact with the first outer polymer film;
- the first fibrous layer comprising a plurality of fibers wherein said fibers are substantially coated with a polymeric binder material that is resistant to dissolution by water and resistant to dissolution by one or more organic solvents;
- c) a central polymer film in contact with the first fibrous layer;
- d) a second fibrous layer in contact with the central polymer film;
- the second fibrous layer comprising a plurality of fibers wherein said fibers are substantially coated with a polymeric binder material that is resistant to dissolution by water and resistant to dissolution by one or more organic solvents;
- and
- e) a second outer polymer film in contact with the second fibrous layer.

A method of forming a fibrous composite material, comprising:
- a) providing a first outer polymer film;
- b) attaching a first fibrous layer to the first outer polymer film;
- the first fibrous layer comprising a plurality of fibers wherein said fibers are substantially coated with a polymeric binder material that is resistant to dissolution by water and resistant to dissolution by one or more organic solvents;
- c) attaching a central polymer film to the first fibrous layer;
- d) attaching a second fibrous layer to the central polymer film;
- the second fibrous layer comprising a plurality of fibers wherein said fibers are substantially coated with a polymeric binder material that is resistant to dissolution by water and resistant to dissolution by one or more organic solvents;
- and
- e) attaching a second outer polymer film to the second fibrous layer.
