Abstract
The transport member of the present invention is a laminate of skin and core layers made of CFRP. The skin layer comprises a prepreg made of a pitch type carbon fiber, oriented by −20° to +20° with respect to a longitudinal direction (X-axis direction) of the transport member, having a tensile elasticity of 500 to 1000 GPa; and a prepreg of PAN type carbon fiber, oriented by +75° to +90° and/or −75° to −90° with respect to the longitudinal direction, having a tensile elasticity of 200 to 400 GPa. As a consequence, a transport member which is light in weight, easy to handle, while being excellent in its bending rigidity, vibration damping characteristic, and heat resistance can be obtained.

A transport member essentially consisting of fiber-reinforced plastic,
- wherein said fiber-reinforced plastic comprises:
- at least one first layer containing a unidirectional reinforced fiber, oriented by −20° to +20° with respect to a longitudinal direction of said transport member, having a tensile elasticity of 500, to 1000 GPa;
- and
- at least one second layer containing a unidirectional reinforced fiber, oriented by +75° to +90° and/or −75° to −90° with respect to said longitudinal direction of said transport member, having a tensile elasticity of 200 to 400 GPa.
A transport member comprising skin and core layers essentially consisting of a fiber-reinforced plastic;
- wherein said skin layer comprises at least two first layers containing a unidirectional reinforced fiber, oriented by −20° to +20° with respect to a longitudinal direction of said transport member, having a tensile elasticity of 500 to 1000 GPa.
A transport member comprising laminated skin and core layers made of carbon-fiber reinforced plastic:
- wherein said skin layer comprises:
- a first layer containing a first carbon fiber, oriented by an angle range of −20° to +20° with respect to a longitudinal direction of said transport member, having a tensile elasticity of 500 to 1000 GPa;
- and
- a second layer containing a second carbon fiber, oriented by an angle range of +75° to +90° and/or −75° to −90° with respect to said longitudinal direction, having a tensile elasticity of 200 to 400 GPa.
