Abstract (en)
[origin: WO2017014718A1] A thermoset composite material and composite railroad crosstie fabricated from the thermoset composite material that comprises a substantially homogeneous blend of an amount of vulcanized rubber particles, polyurea binding agent and urea melamine. The thermoset composite material may also contain a granulated silica material. The thermoset composite material may comprise about 30% to about 50% by weight of the vulcanized rubber particles, and it is subjected to compression molding at a predetermined temperature and pressure for a resident time period forming the composite railroad crosstie. The thermoset composite material and railroad crosstie may further comprise a fibrous glass material in the form of unbundled fibers and/or one more glass mats encapsulated within the thermoset composite material. In addition or alternatively, an elongated core insert may be encapsulated in the thermoset composite material.
