Abstract

On joining a fibre-reinforced plastic part, such as a plastic fibre-reinforced robot arm, to a functional element such as a gear, as a result of the flow characteristics of the plastic in the case of a high pressing action or high pressures, the joints are no longer stable or resistant and instead tend to loosen. To obviate this problem, the invention provides a fibre-reinforced plastic part, in which several metallic parts (6) engage through at least one fibre-reinforced shoulder (4). On one side of the shoulder or shoulders (4) is provided at least one metallic abutment (8) engaging over several metallic parts (6) and a functional element (2) is braced from the opposite side of the shoulder or shoulders (4) with the abutment (8) against the front ends (6a), facing the latter, of metallic parts (6).
