In addition to fibre glass reinforced cores of composite long rod insulators, also tubes manufactured by the filament winding method are now in use as parts of post type insulators, housings or in dry-type transformer bushings. It is well known that the interface between the fibres and the resin matrix is very important both for the mechanical and the electrical properties. In this paper results are presented which verify the importance of a high quality interface expecially in the case of electrical treeing. The influence of voids in the composite is also regarded. It is assummed that the interface areas play a decisive role also for the water transport into composi te materials. Therefore, the moisture absorption is investigated and first results are presented.
