Abstract
A method for producing a composite part is provided. The method comprises compacting a powder composition comprising a lubricant into a compacted body; heating the compacted body to a temperature above the vaporization temperature of the lubricant such that the lubricant is substantially removed from the compacted body; subjecting the obtained heat treated compacted body to a liquid polymer composite comprising nanometer-sized and/or micrometer-sized reinforcement structures; and solidifying the heat treated compacted body comprising liquid polymer composite by drying and/or by at least one curing treatment.
Claims17
A method for producing a composite part, the method comprising:
- compacting a soft magnetic powder composition comprising a lubricant into a compacted body;
- heating the compacted body to a temperature above the vaporisation temperature of the lubricant such that the lubricant substantially is removed from the compacted body;
- impregnating the obtained heat treated compacted body with a liquid polymer composite comprising carbon nanotubes, wherein prior to impregnation the obtained heat treated compacted body has a density above about 7.0 g/cm3;
- and
- solidifying the heat treated compacted body comprising liquid polymer composite by drying and/or by at least one curing treatment.
