<P>PROBLEM TO BE SOLVED: To provide a fuel hose, which has superior fuel low transparency, and also has low cost, has superior interlayer adhesion, softness, low-temperature impact resistance, and heat resistance. <P>SOLUTION: The fuel hose has a tube-shaped inner layer 1 composed of the following (A), and an outer layer 2 which contacts with the outer peripheral surface of the inner layer and is composed of the following (B). Bridge structures formed by electronic beam bridging are employed to both layers, and the fuel hose is formed by being interlayer adhered with the layers. (A) is a resin composition which has an aromatic polyamide resin as a main component and contains a monomer of the following (a). (a) is a monomer which has a vinyl group and whose glass transition temperature (Tg) of its bridged product is not higher than 0°C. (B) is a resin composition which has a polyolefin-based resin as a main component and contains a monomer of the following (b). (b) is a monomer which has a vinyl group and whose glass transition temperature (Tg) of its bridged product is ≥30°C. <P>COPYRIGHT: (C)2012,JPO&INPIT |
