  • Patent number: 4989643
    Abstract: A high performance composite hose having enhanced durability, reliability and longevity for use in high pressure, high temperature and/or vibrational environments such as turbocharged truck, bus, automobile, marine and generating engines. The composite hose comprises one or more plies of balanced fabric having a high performance elastomer adhered to the inner and outer surfaces of each fabric ply. The balanced fabric is formed as woven sheets from filament yarns resistant to high temperatures. Balanced fabric sheets are sectioned at a predetermined angle to the filament yarns to form balanced fabric plies. The yarns of the balanced fabric plies are orientated at the predetermined angle with respect to the longitudinal axis of the composite hose such that the composite hose has a predetermined longitudinal flexibility to compensate for stress effects resulting from high temperatures, high pressures and/or vibrations.
