Planar component i.e. carbon fiber component, for assembling spacers for forming space boundary to separate inner space and outside space of motor car, has supporting ring inseparably and edge-sidedly connected with body of component

摘要

The component (1) has a body (3) made of first material i.e. fiber reinforced plastic, and a transit region (5) provided with a planar supporting ring(10) that is made of second material. A through hole (13) is inserted with a spacer (30), and the supporting ring comprises a connectable sleeve (20) for guiding the spacer, where the connectable sleeve is made of third material. The supporting ring is inseparably and edge-sidedly connected with the body of the component. The supporting ring comprises a permanently smooth and corrosion resistant surface (12).
