Abstract: A propeller shaft for automobiles comprises a cylindrical-shaped body (1) of fiber reinforced plastics and a joint (2) press fitted into and joined to both ends of the body, said body (1) comprising a main layer (1a) extending along the entire length of the body (1) to enclose reinforced fibers which are helically wound at an angle of +/-5 to 30 DEG relative to an axial direction of the body, and a partial layer (1b) formed integral with and provided inside the main layer (1a) to enclose hooped, reinforced fibers. The joint (2) has an inclined surface (2c) extending downward toward an interface between the joint (2) and the body (1) or an upright surface (2d) having an outer diameter equal to or smaller than that of the partial layer (1b) and abutting against an outer end surface of the partial layer (1b) or a wedge (2f) having a tip end thereof opposed to an interface between the main layer (1a) and the partial layer (1b). When a compressive load is applied on the joint (2) in an axial direction, the inclined surface (2c), upright surface (2d) and the wedge (2f) separate the main layer (1a) from the partial layer (1b), so that breakage of the body (1) progresses whereby an energy absorbing effect owing to the body of a crushable construction is displayed.

Abstract: PURPOSE:To make crash destruction progress by providing a wedge means including a main layer extending along the whole length of a FRP cylindrical main body and a partial payer inside the main layer integrally therewith for causing a joint to apply an axial direction compressing load between the main layer and the partial layer and to peel these. CONSTITUTION:When an axial direction compressing load is applied to a propeller shaft, a joint 2 is pushed to a main body 1 side, a wedge 2d is pushed in between a main layer la and a partial layer 1b and a spreading distortion of a circumferential direction is generated on the main layer 1a by the function of the wedge Since spreading destruction expansion for the main layer 1a is smaller than that for the partial layer 1b, only the main layer 1a is destroyed and inter-layer peeling between the main layer 1a and the partial layer lb occurs. The destruction of the main layer 1a is greatly advanced by a projecting part 2c. However, no destruction occurs on the partial layer lb connected to the joint 2 and this moves in an axial direction in the main body 1 together with the joint 2 while destroying the main layer 1a. Thus, satisfying such basic requirements as strength, the number of dangerous revolutions and the like, destruction is surely progressed while matching the destruction of a body at the time of crash.
