    Abstract: A composite wire or thread-based reinforcement is coated with rubber and may be used for reinforcing a finished rubber article, such as a tyre. The reinforcement includes one or more textile or metallic reinforcing wires or threads, and a coating rubber that coats each wire or thread. The coating rubber is formed of a rubber composition that includes at least one diene elastomer, a reinforcing filler, between 10 and 150 phr (parts by weight per hundred parts of elastomer or rubber) of a platy filler, and a crosslinking system. The coating rubber has improved water-barrier properties, thus giving the composite wire or thread-based reinforcement better protection against corrosion or ageing due to penetration of water, for example through tyre tread.

    Abstract: A reinforcing cord of the present invention is a reinforcing cord (10) for rubber reinforcement including a fiber core (11) and a plurality of strands (12) disposed around the fiber core (11). The fiber core (11) is formed of one or a plurality of highly elastic fibers having a tensile elastic modulus of at least 100 GPa. Each of the plurality of strands (12) is formed of a plurality of glass fibers that are primarily twisted, and the plurality of strands (12) are finally twisted to be disposed around the fiber core (11). The direction of the final twist of the plurality of strands is opposite to the direction of the primary twist in each of the plurality of strands (12). The number of final twists of the plurality of strands (12) is 1.0 to 3.0 times/25 mm, and a ratio of the number of primary twists in each of the plurality of strands (12) to the number of final twists of the plurality of strands (12) (the number of primary twists/the number of final twists) is in a range of 1.5 to 2.5.
