Abstract
A fiber-reinforced polymer composition that comprises a polymer matrix; a thermally conductive filler distributed within the polymer matrix; and a plurality of long fibers distributed within the polymer matrix is provided. The long fibers comprise an electrically conductive material and have a length of about 7 millimeters or more. Further, the composition exhibits an in-plane thermal conductivity of about 1 W/m-K or more as determined in accordance with ASTM E 1461-13 and an electromagnetic shielding effectiveness of about 20 dB or more as determined at a frequency of 1 GHz in accordance with EM 2107A.
Claims25
A fiber-reinforced polymer composition comprising:
- a polymer matrix;
- a thermally conductive filler distributed within the polymer matrix;
- and
- a plurality of long metal fibers distributed within the polymer matrix, wherein the long fibers have a length of about 7 millimeters or more and constitute from about 1 wt. % to about 20 wt. % of the composition;
- wherein the composition is formed by forming a first masterbatch that comprises long fibers distributed in an aligned fashion within a polymer matrix;
- forming a second masterbatch that contains a thermally conductive filler distributed within a polymer matrix;
- and
- combining the first masterbatch and the second masterbatch to form the fiber-reinforced polymer composition;
- wherein the composition exhibits an in-plane thermal conductivity of about 1 W/m-K or more as determined in accordance with ASTM E 1461-13 and an electromagnetic shielding effectiveness of about 20 dB or more as determined at a frequency of 1 GHz in accordance with EM 2107A.
