Tire
According to a tire comprising a CFRP comprising a matrix resin and a carbon fiber, in which the matrix resin comprises a resin component comprising 20 to 80% by mass of an epoxy resin and 20 to 80% by mass of a functional group-modified acrylonitrile butadiene copolymer, it is possible to provide a tire which is lightened while maintaining the strength of a tire with a steel cord and/or a bead wire.
1. A tire comprising:
a carbon fiber reinforced resin comprising a matrix resin and a carbon fiber, wherein the matrix resin comprises a resin component comprising 30 to 80% by mass of an epoxy resin, 20 to 70% by mass of an amino group-modified acrylonitrile butadiene copolymer and a curing agent.
2. The tire of claim 1 , wherein the matrix resin is a matrix resin having an initial elastic modulus of 0.1 to 1,000 MPa and an elongation at break of not less than 50% and being free from yield at a degree of elongation of 50%.
3. The tire of claim 1 , wherein the tire comprises a bead core formed from the carbon fiber reinforced resin.
4. The tire of claim 1 , wherein the tire comprises a bead core formed in part from the carbon fiber reinforced resin.
