Method and system for forming composites
There is provided a method and system for forming a composite material. The method includes: combining a first component element with a second component element to form a composite mixture; subjecting the composite mixture to a first force to in order to form ligaments and disperse the first component element and second component element in relation to each other, wherein the first force is a mechanical force, subjecting the ligaments to at least one second force in order to form attenuated ligaments and further disperse the first component element and second component element in relation to each other, wherein the at least one second force imparts both shear flow deformation and extensional flow deformation to the ligaments to form the attenuated ligaments; and collecting the attenuated ligaments. There is also provided a composite material prepared using the method described above.
1. A method for forming a liquid composite material, the method comprising:
combining a first component element with a second component element to form a liquid composite mixture;
inserting the liquid composite mixture into a feeder configured to deposit the liquid composite mixture onto a rotating surface;
charging the liquid composite mixture prior to the liquid composite mixture being deposited onto the rotating surface;
subjecting the liquid composite mixture to a first force on the rotating surface to form liquid ligaments and disperse the first component element and second component element in relation to each other, wherein the first force is a mechanical force;
subjecting the liquid ligaments to at least one second force to form attenuated liquid ligaments and further disperse the first component element and second component element in relation to each other within the attenuated liquid ligaments, wherein the at least one second force comprises centrifugal force and electrostatic force and the at least one second force imparts both shear flow deformation and extensional flow deformation to the liquid ligaments to form the attenuated liquid ligaments; and
collecting the attenuated liquid ligaments on a collection surface, the attenuated liquid ligaments coalescing on the collection surface to form a well-dispersed, heterogeneous bulk material as the liquid composite material.
2. The method of claim 1 , wherein the at least one second force is a continuation of the first force.
3. The method of claim 1 , wherein the first component element is viscoelastic material and the second component element is a filler.
4. The method of claim 3 , wherein the viscoelastic material is a polymer.
5. The method of claim 1 , wherein the first force comprises centrifugal force and the at least one second force comprises centrifugal force and electrostatic force.
6. The method of claim 1 , wherein, on the rotating surface, the liquid composite mixture forms a film.
7. The method of claim 1 , wherein charging the liquid composite mixture prior to the liquid composite mixture being deposited onto the rotating surface includes charging the liquid composite mixture in the feeder.
8. The method of claim 7 , wherein charging the liquid composite mixture in the feeder is by connecting the feeder to a voltage source.
9. The method of claim 1 , wherein inserting the liquid composite mixture into the feeder includes passing the liquid composite mixture through a static mixer of the feeder to enhance mixing of the first component element and the second component element.
