Abstract
The present disclosure relates to a plastic composite resin composition, a method of manufacturing a plastic molded article using the same, and a plastic molded article for radar absorption manufactured using the method. More particularly, the present disclosure provides a method of improving a radar absorption rate by manufacturing a plastic molded article having pores formed therein using a plastic resin including polyamide, a filler including carbon nanotubes, and a foaming agent.
Claims3
A method of manufacturing a plastic molded article for radar absorption, the method comprising:
- preparing a plastic composite resin composition comprising a plastic resin and a filler, wherein the plastic resin comprises polyamide;
- adding a foaming agent to the plastic composite resin, followed by mixing and injection molding, thus forming a molded article;
- and
- manufacturing a foaming molded article by performing foaming using the foaming agent to form pores in the molded article,
- wherein the pores have a long axis length of 0.3 to 1.0 mm.
