Abstract
A main body of a hollow cylindrical member is formed of a wound preimpregnation sheet made of reinforcing fibers impregnated with synthetic resins. A synthetic resins layer with a metallic member is provided onto an outer periphery of the main body for reinforcing and/or decorative property. The metallic member is in the form of a thin film bonded to an outer periphery of the synthetic resins layer or a net-like metallic member embedded in the layer.
Claims8
A hollow cylindrical member comprising:
- an inner layer formed of a fiber-reinforced resin, said layer being formed of carbon fibers defining a color;
- an intermediate layer wound and formed onto an outer periphery of said inner layer and made mainly of a fiber-reinforced resin utilizing glass fibers as reinforcing fibers, said fibers being arranged to intersect one another;
- a thin metallic film provided on an outer surface of said intermediate layer opposite from said inner layer;
- and
- an outer layer integrally wound and formed onto an outer periphery of said thin metallic film and said intermediate layer and made of a fiber-reinforced resin utilizing as reinforcing fibers glass fibers which are arranged in parallel relation to each other in a longitudinal direction of said hollow cylindrical member.
