Abstract
A fiber-reinforced rubber article has a rubber body portion with a fiber reinforcement embedded therein. The fiber reinforcement includes a plurality of tubular braided cords braided by yarns. Each of the tubular braided cords is braided by more than three yarns at a braid angle in a range between 10.degree. and 35.degree., wherein said braid angle is an angle between a yarn of the tubular braided cord and the axial line of the tubular braided cord. Each tubular braided cord also has a fistulous center hole defined by the tubular braided cord.
Claims19
A fiber-reinforced rubber article, comprising:
- a rubber body portion;
- and
- a fiber reinforcement embedded in said rubber body portion, said fiber reinforcement comprising a plurality of tubular braided cords braided by yarns, each said tubular braided cord being braided by more than three yarns at a braid angle in a range between 10.degree. and 35.degree. wherein said braid angle is an angle between a said yarn forming said tubular braided cord and the axial line of said tubular braided cord, and each said tubular braided cord having a fistulous center hole defined by said tubular braided cord.
A fiber-reinforced rubber article, comprising:
- a rubber body portion;
- and
- a fiber reinforcement embedded in said rubber body portion, said fiber reinforcement comprising a plurality of tubular braided cords braided by yarns, each said tubular braided cord being braided by more than three yarns at a braid angle in a range between 10.degree. and 35.degree., wherein said braid angle is an angle between a said yarn forming said tubular braided cord and the axial line of said tubular braided cord, and wherein said rubber body portion defines an endless belt having a direction of elongation and said fiber reinforcement is embedded with the axial lines of said tubular braided cords extending in said direction of elongation.
A fiber-reinforced rubber as claimed in 16, wherein said endless power transmission belt is a synchronous belt, and said rubber body portion includes a belt base comprising an elongated rubber layer and a plurality of teeth formed on one side of said elongated rubber layer and made of the same material as said elongated rubber layer, said fiber reinforcement being embedded in said elongated rubber layer.
