| description | The invention discloses a fiber directional filling polytetrafluoroethylene material and a preparation method thereof, and the preparation method comprises the following steps: adding magnetic nanoparticles into a fluororesin emulsion, uniformly dispersing, then adding fibers, fully stirring, carrying out vacuum filtration to obtain magnetic fibers, drying the magnetic fibers, and carrying out ball milling to obtain powder; stirring the magnetic fiber powder and polytetrafluoroethylene at a high speed by using a high-speed mixer, and uniformly mixing to obtain a composite material; in the processing process, a magnetic field is annularly arranged around a mold, the composite material is added into a funnel with sieve pores, the material is slowly added into the mold, so that magnetic fibers have sufficient time and space to deflect under the action of the magnetic field, and then the magnetic fibers are pressed into the directionally arranged fiber reinforced composite material according to a specific pressin |
