ABSTRACT:
To increase the strength of a helical spring with a spring wire made of thermosetting plastic in which reinforcing fibers are embedded that run at an angle of approximately .+-.45.degree. to the longitudinal axis of the spring wire, the fibers are present as a fabric that is wound helically around the longitudinal axis of the spring wire, with the warp and woof threads being at an angle of approximately 45.degree. to the longitudinal axis. A process is also proposed for producing such helical springs.
