An ultrasound probe of the present invention has a piezoelectric element and a backing material disposed on one direction side with respect to the piezoelectric element, the backing material containing heat conductive particles. The backing material has a heat conductivity of 2.0 W/mk or more, and the content of the heat conductive particles is less than 30 vol % based on the total volume of the backing material.

A fiber reinforced composite component may include interleaved textile layers and ceramic particle layers coated with matrix material. The fiber reinforced composite component may be fabricated by forming a fibrous preform and densifying the fibrous preform. The fibrous preform may be fabricated by forming a first ceramic particle layer over a first textile layer, disposing a second textile layer over the first ceramic particle layer, forming a second ceramic particle layer over the second textile layer, and disposing a third textile layer over the second ceramic particle layer.

A particulate build material for three-dimensional printing can include from about 80 wt % to about 99.5 wt % of a polyamide particles, and from about 0.5 w % to about 7.5 wt % of thermally conductive particles including cubic lattice structured particles of carbon, cubic lattice structured particles of boron and nitrogen, or a combination thereof.

A method of fabricating a polymer composite material by mixing a polymer material with a planar material, depositing the mixture on a substrate, and stretching the resulting thin film, is described. Polymer composite materials produced using said method and ballistic resistant materials comprising said polymer composite materials are also described.
