Claims
- 1. An electrically conductive composite filter structure comprising:
- a first fiber mat having fibers made of an electrically conductive material, said fibers being arranged so that said first fiber mat conducts an electrical charge therethrough;
- a polymeric material impregnant distributed substantially throughout said first fiber mat wherein each fiber of said first fiber mat is substantially completely coated by said polymeric material, said polymeric material forming a substantially monolithic structure holding said first fiber mat in partial compression so that said first fiber mat has a porous center portion and a non-porous periphery which defines an integral housing, and
- a source of electrical power connected to said first fiber mat.
- 2. An electrically conductive composite filter structure as recited in claim 1, further comprising:
- a second fiber mat having fibers made of an electrically conductive material, said fibers of said second fiber mat being arranged so that said second fiber mat conducts an electrical charge therethrough; and
- a polymeric material impregnant distributed substantially throughout said second fiber mat, wherein each fiber of said second fiber mat is substantially completely coated by said polymeric material, said polymeric material forming a substantially monolithic structure holding said second fiber mat in partial compression so that said second fiber mat has a porous center portion and a non-porous periphery, said second fiber mat being connected to said source of electrical power.
