Abstract Scope |
The production of filaments composed of polymer with embedded magnetic particles is usually performed by mechanical mixing the polymer and the functional material (i.e. with a kneader, which requires large scale equipment) or purchasing pellets of composites, which limits the compositional possibilities to those provided by industrial suppliers. In order to be able to fabricate parts with uniform characteristics, filaments with uniform distribution of particles are needed. One of the major limitations at the laboratory scale is the loss/agglomeration of magnetic powder in the hopper. We propose an original procedure to prepare composite filaments using customized polymer capsules filled with soft magnetic steel particles as the initial feedstock for the extrusion of the composite filaments. This method, not only limited to the addition of metallic particles, does not require a sophisticated machinery and allows desired compositions at the laboratory scale with good control of the amount of particles being added. |
