METHOD AND APPARATUS FOR INFILTRATION OF A MICRO/NANOFIBER FILM

摘要

There is provided an apparatus and method for manufacturing of an infiltrated fiber-based composite film. The apparatus comprises two tool blocks arranged opposite each other enabling a fiber-based film to be arranged between the tool blocks. At least one of the tool blocks comprises a recess so that the recess can form a sealed cavity enclosing a portion of the film when the tool blocks are in contact with each other. At least one of the tool blocks comprises a vacuum channel connecting cavity to a vacuum pump for drawing a vacuum in the cavity; a melt channel connecting the cavity to a source of molten material. The melt channel comprises a valve arrangement controlling delivery of the molten material to the cavity; pressure means to achieve an elevated pressure onto the molten material within the cavity such that a fiber film in the cavity is infiltrated by the molten material; and an ejection piston for ejecting an infiltrated fiber film from the cavity.
